Do ice baths help recovery?

They ease soreness a little, but after lifting they can blunt muscle and strength gains, so save them for busy competition periods.

Cold water after lifting dampens the signalling in muscle that drives growth. Pooled studies show smaller gains in muscle size and in strength, both small effects from a limited number of trials.

When you have to perform again within a day or two, less soreness can be worth that cost. When the goal is to build muscle or strength, skip cold water in the hours after lifting.
