I think it's pretty hard to claim any sort of trend at all when you're talking about a 10-year period that spans four different baseball department heads (if you count Gillick 2.0 as one of them) and three different scouting directors.
Barber's reign has seemed more situational than anything, in terms of team goals/needs, draft position and also the specific pick. Abel was thought to be a possible steal given his youth and lack of experience (due to COVID); had they not felt he was a good value there probably they would have taken a position player (five of the next six guys taken after him were non-pitchers).
I also feel like Barber's first drafts were reactive to his predecessor - taking two HS pitchers on the heels of two college position players who already looked like they were going to work out in 2020. Before Bohm and Stott the Phillies also took position players three previous years in a row. During much of that time the team believed it already had the makings of a homegrown (if mostly trade-acquired) pitching staff, and it kind of did, in that Eflin, Pivetta and Ben Lively were all still credible major league starters last year, and Velasquez did give them innings (with Thompson being the big flop). In the end they also traded both Sanchez and Howard.
Then Barber reacted to his own drafts and the team's seeming depth by pivoting to HS position players, having stocked up on pitching at the top in '21 (and with two of the four picks in '20).
When you factor in the 2020 draft and the subsequent changes to the draft the Dombrowski/Barber data set is small, and any larger data set is full of variables.
