Without researching much, one thing about each of those nine:
Gil: Back from arm surgery, big arm, could be a multi-inning guy in NY or rotation in AAA.
Beeter: The guy they got from LAD for two months of awful Gallo in Aug 2022, 165 Ks in 132 innings last year in AA/AAA, projected role similar to Gil's.
Rice: The only one of these nine not on NY's 40 man currently, doesn't need to be protected yet as a 2021 12th round pick. He's a Dartmouth boy who blew up in AA down the stretch last year, 16 HRs in 196 ABs. He splits time between C/1B and NY is thin at 1B behind Rizzo (with DJ as the regular 3B especially), so he could maybe hit his way into a role.
Rortvedt: It's still not a hundred percent clear that he is out of options but assuming he is, he is only still on the 40 man in case Wells or Trevino aren't healthy Opening Day. NY still has 5 catchers on the 40 man, Narvaez will get Rortvedt's role as 3rd string (he has all three options) and Agustin Ramirez is a longer-term project who almost certainly won't be able to help this year. NY also has Luis Torrens assuming he doesn't opt out, so we may be nearing the end of the illustrious Rortvedt era.
Cabrera: This is a good one, he is a switch-hitter but a much better hitter from the left side, so this year they plan to have him hit lefty against some lefties and righty against some lefties.
Volpe: Last year he had an all or nothing selling out for power approach at the plate, this year he is reportedly trying to get back to the alley to alley slashing that made him a top 5 MLB prospect. He is still 22, 23 in April.
Grisham: The other OF they got from SD along with Soto, he is as good defensively as any CF in the game currently, in the Kiermaier/Bader range. He hits lefties better than righties despite being a LHH, but that will work out well for a platoon (with position switching) with Verdugo who as you all know cannot hit lefties.
Jones: Another Winfield/Judge-sized giant, he is somehow one of the fastest runners in the sport. His peak home to third time last year was identical to Corbin Carroll's best, which I think was best in MLB.
Pereira: He looks like the odd man out to start the year in the OF if everyone is healthy (Judge/Soto/Verdugo/Grisham plus the newly sleek Stanton, plus Cabrera), but regular AAA ABs will be good for him. He is still a top 100 guy on some lists, also still 22, 23 in April. I'm glad NY didn't sell low on him (yet anyway), he might not pan out but he has big upside if he does.
