Here's who has been helped (or hurt) by the shift limits

mlb.com

One half of the way through the first season with baseball’s new shift limitations on the books, the rules have done more or less what they were expected to do.

They’ve definitely made some impact (batting average on balls in play is up by 7 points), but not by an earth-shattering amount (it’s only back to what it was in 2018-'19). It's helped very specifically on certain types of balls (pulled grounders and liners from lefty batters, which are up by 36 points), while not affecting strikeout rates (which are slightly up, though not by much).

By evaluating Statcast data in a similar way as we did back in the spring when previewing who might be most likely to benefit, we’ve been able to come up with a list of the hitters who have gained the most hits that were likely due to positioning.

Nota bene (from the link): Estimates based on Statcast data, since there’s never going to be an entry in the box score that reads this exact ball definitely wouldn’t have been a hit last year.
