Everything can be redeemed, even devils and demons.
Another problem you face is institutional violence. A goblin might be totally redeemable, but so programmed by his culture and kin that he tries to kill you even when you offer him mercy. Thats a tough one, because he's not evil by our metric. He doesn't like kicking puppies, but thinks he must because [reasons].
So pick your "battles" and accept that your party is going to kill most enemies. You only have screen time to redeem the big ones - a few major villains, and a few beloved NPCs at most. Know the local resources like shelters, mentors, etc to offer to NPCs. And make sure to share the spotlight.
Why limit redemption? Why not play the redemption paladin who knows that goblins, devils, and demons are evil to the core, but strive to redeem them anyway because it's the right thing to do? The ends never justify the means.
That's how I'd play it, anyway.
It's certainly possible to try, but it should be done in a way that respects the time of other players. If they are cool with it, then redeem all the things. But I've seen more than one table have 'the talk' with a redemption paladin player.Why limit redemption?

Very few groups enjoy everything you do to the full extent that you do. Cooperating despite reasonable differences is a good skill to have!Play with a group who enjoys the things you do. Else find/start a new group.
