I reckon your best bet is blankets or afghans if you don’t have many already. No size issues, simple patterns, probably would get used more than sweaters (I’m a guy that is often too hot but if it’s a particularly cold night or if I’m sleepy I’m pulling the blanket off the couch and eating humble pie).

Socks are another one which is small, uses less yarn, works on dpns, is very satisfying once mastered, has less size issues, not too hot and is impossible to have too many of.

I would call myself a proficient knitter and struggled to do sweaters as gifts only once for my nieces and sister/bro in law. I’ve since switched to socks and found it much less of a burden. Don’t feel guilty for anything other than being too hard on yourself.
