I recently replaced my brake pads and rotors thinking it was worn out, but they weren’t even too bad but there’s this squeaking sound that keeps coming from the right front tire when it’s on 20 to 30 miles or when I brake.

Squeaks from new pads are generally related to the harmonics of the pad as it wipes the face of the rotor. Sort of like fingernails on a chalkboard. Has to be just right for it to work.
Commonly the solution is to do 2 things, one, pull the wheel back off and pull the caliper back off, clean everything and make sure the caliper slides are working and the pads are free to move and that the pad shims are there, now apply either some brake grease or anti squeal goop to the caliper piston face where it contacts the inner pad and to the outer caliper ears where they touch the outer pad. Reinstall the caliper and lightly touch the brake pedal, if you used grease you can drive now, if you used the goop they sell (basically high temp silicone sealer really) then let it set an hour or so for that to set up. Now the second step is to wipe down the inner and outer face of the rotor with brake clean on a rag, even greasy fingerprints can be an issue. Also check that the backer plate isn't close enough to touch. Put it back together. See if the noise is gone, now do the other side because you have OCD that it might have an issue LOL.
