This bit is what stands out to me, OP:
I don’t care one jot for travelling or furthering my career or spending hours pampering myself or going to nice restaurants.
It sounds as though you think 'committing' shouldn't involve you doing any of those things, when plenty of people in committed relationships are also travelling or working hard or going out to nice places.
Or someone who is really into drinking or travelling like that’s their main priority.
Drinking, fair enough obviously, but if you're looking for someone who isn't into travelling, eating out, their career, or looking their best (gym, etc?) then what are you looking for? Someone in a job they're not bothere about progressing, doesn't want to have new exciting experiences with you, doesn't want to go out for dates with you, doesn't enjoy you both getting dressed up...?
I wonder if you've got this idealised idea of 'settling down and being committed' as not having any external influences or life factors involved. And it's okay if you want that, but lots of people don't have that life set-up. When I met DH, he lived on the other side of the country and was about to change jobs. But I liked him, not his life situation specifically, and I gave it enough time to see if we worked well enough together to see if it would be worth pursuing.
Again, it's fine to have your requirements for a partner if you don't want that level of hassle (god knows I never want to drive that motorway between DH and I's hometowns ever again!) but don't just assume commitment = sensible, safe, no potentially changeable life factors at all and overlook people who might actually be great for you.
Having said that - your requirements in a relationship are entirely yours to have, and I don't think you should compromise them entirely. But maybe don't write off people who have particular interests if they're otherwise lovely and have potential.
