Ideally I would like to work with flowers even though I have no experience I really like them and think it’s quiet but I think these are few and far between.

It's usually seasonal work and the pay is probably bad, but look into horticulture roles with your local/regional parks departments. It's the only job I've had where I've gone home feeling like I did something good every day. I plant flowers for the benefit of people who will never pay me, the public constantly compliments that work, and the moment I get off work to walk my dog I'm my own customer. Everyone there was motivated by values like environmental stewardship and community so it's a super supportive workplace that's more conscious of labour/discrimination laws. In terms of training/degrees, most of my coworkers have no formal horticulture background and the department pays for their training.

If you don't have transportation and public transit is not available... maybe some "call center from home" type work?

Got a job at a the post office and have had to call IT Help and pretty sure that, in every call, I've heard background noises that were house noises.

I personally LOVED receiving pallets of stuff when I worked at a grocery store. Super satisfying to tear down a mountain of boxes and making everything go to their places.

Not sure its a common job, but I stumbled into a "work in a university's archeological collections department taking pictures of random samplings of whatever random things were in boxes held in storage from decades ago". Everybody hated doing the camera work because it was tedious and meticulous but kinda loved it.

Outside of me telling bosses, "if you put the tools in front of me with instructions on what to do with them and some way to talk to you when there's problems I cannot solve on my own, you'll probably never have a problem with me", none of my previous job experiences were applicable and I went in with no special training or certifications relevant to the position.

I've had a lot of fun as a tour guide and you'd be surprised how NT-friendly the job can be. You need to be able to become comfortable talking to a large group of people, but on the plus side normal social conventions do not apply.
People are there to hear you yap about something you know about. You can't really commit a faux pas, there's a clear framework for the conversation, what topic it is, what relation you have to the people on the trip, what is expected of you, how long it is expected you do it and so on. I can recommend it.

Working in demolition was also a lot of fun, though you need to be able to take care of yourself (wear PPE even though you're told it's gay or some stupid shit like that.) It's also not something I'd recommend you do for more than 6 months, it wears out it's welcome or it wears out you.

Stay out of kitchens if you can.

I've done a lot of rigging - setting up stages and the like. It's been nice work and easy to work your way up.

Working with kids was very chill. Can recommend. Protip to interacting with children: Treat them like your drunk friends. The behaviour is more or less similar.

Depending where you are you can get training as a sailor or a truck driver and be paid for it.

There might be greenhouses near you that sell plants. They typically give out courses as well and they might be looking for hires too.
I guess check if you live near a botanical garden too

You can inquire about jobs at local flower shops if you want

landscaping work can pay decent, keep you fit, little human interaction and working with plants

Warehouse pays better than retail and you don't have to deal with customers. If you work in a large warehouse you can basically dissappear into the background

Legal weed work hires with no education and is sort of like working with flowers

Trade work.

UPS package handler/warehouse jobs are pretty good from what I hear, but it's fairly hard work. It's part time, but it has benefits, a union and has opportunities to get extra hours. I think it pays the same $21 starting pay everywhere, which is good for my area at least.

Absolutely no qualifications needed, you just apply online when they have openings and they give you a start date.

according to brain-haver mark cuban, you could be an AI prompt engineer

I don’t know what kind of flower job you have in mind, but I was offered a job at an orchid greenhouse and I had zero experience or knowledge in it. I had to move out of the area so I didn’t take the job. There’s plant nurseries, garden departments, flower shops…. 420 operations depending on your area.

I've got an autistic friend who works in a sexshop and really loves it. She says it's very chill.

Another friend has worked as a night guard for a good while. Very chill, he just reads books and looks at a TV screen while getting paid well.

IDK how things are in your area in this regard, but what you need to get a software development job can be made/achieved without a degree.

Namely, you need to make a portfolio of projects on GitHub or analogous platform. Those projects should demonstrate your ability to work with relevant technologies and understanding of some of the relevant concepts.

A way to look up relevant technologies and skills is to go to a job-searching website and read the requirements of relevant jobs.

Retail or fast food as much as those jobs suck. My first job while I was in college was retail and I stayed after I dropped out.
