It actually is -

-I’m not interested in having kids, so I’d want a partner that feels the same.
-I like exercising, so I’d want to be with someone who does as well, particuarly if they’re into (insert physical hobby you enjoy)
-I like to go out and do (insert activities in meatspace that often involve meeting people), so I’d be interested in someone who likes to do that kind of thing over just sitting at home scrolling the internet.

These are good qualifiers that more or less equate to the same thing as OP states without coming across like a dick. From there, if someone was to introduce someone to OP, they can make a further determination of compatibility, and if someone doesn’t match due to the blunter version of the above it can be as easy as “I didn’t really feel a connection, [and unless she’s actually kind of a bitch] but she’s a great person and I hope she meets someone awesome”.

Edit: That said, if you’re the version of yourself that doesn’t match what you’re looking for, you should be working on that before seeking a partner IMO.
