guys you meet on the dating apps will be focussed on dating/sex/booking out their weeks with chatting to women and arranging meets. That's why they're on a dating app
Apart from work they will be busy chasing and chatting to women.
They tend to keep their interests and hobbies separate from the women they are chatting to (if they have any). "Dating" takes up a lot of time and energy.
The interests they put on their profiles are often complete nonsense or you never actually see them doing them.
If you find some networks in your city or local area, the men who are regularly committing the time to turn up to a book club or language meet will have those interests.
Especially if the activity needs some preparation and commitment or vetting.
If it's just an easy access meet, everyone is judging on looks or first impressions a good job title.
So if it's a hiking group with an easy hike, or a meet in the pub, there's less screening and more people just looking for a date.
however, if everyone (including you) has to make an intellectual or time commitment then you'll get people who have done the same. Less people but more in common.
it's a different vibe - the guys tend to be less highly sexed or pushy but if you want to get to know someone slowly, friends first, things on common, this may be the way?
Of course, avoid groups if there's hardly anyone there or not many new people or an unfriendly or closed vibe.
But if there's regularly new men and women and people actually chat, then stick with it. Location may help - city centres can be better for this.
If you're regularly socialising with a lot of people who have certain interests and values and lifestyle, it really increases the chances of meeting a date with those interests and values.
