My first bike was a Suzuki GN250 and I’d highly recommend it (or something similar) to you based on your post. Eg Honda CB250/CD250. Actually any Japanese (UJM) air cooled single cylinder bike will be a great start to learn riding and maintenance. Usually cheap and available parts too.
I now ride a DR650 and still do a lot of my own wrenching.
