i use a couple sprays of this coconut oil hair stuff that doesn't really do much to my hair or beard, but it smells nice if you're up close

i also invested in a fancy cologne (versace eros) that i really like. i got a big bottle, and i use one spray a day (anything more and i get self-conscious about smelling too strong), and i've used maybe a quarter of it in the last year. that being said, i think you could get a great cologne or perfume without spending nearly as much, for example, in the fragrance section of a wal-mart or pharmacy type store. and really there's no objectively "good" fragrance, so i think going to a store and comparing the scents of some different options in a price range that's affordable for you is a great way to start on the smell good journey :) even spending a couple minutes smelling and comparing different body washes, shampoos, or lotions could go a long way to get you started!
