Well let's examine every ball in SWSH.
Quick ball- it's not for raid battles. 100%
Pokeball- nothing to say 1 catch rate is bad (even great ball and primier ball are similar and same respectively so I'll not cover that.)
Ultra ball- it's standard ball in late game. It all right I guess, but rarely works for me. (Might work for you)
As pulse said, repeat ball, dusk ball, dive ball and net balls work a little better than above pokeballs if their requirements are met. But not timer ball. In 5 star Pokémon raid battles you only have 10 turns. Just 1 time boost isn't that good.
Repeat ball is the best in these though with 9% chance to catch bosses.
Finally the best one:
Master ball - literally nothing to say, it will catch any Pokémon without fail and use it if you want for one Pokémon that's most difficult.
Hope I helped!
