I've used carbon steel knives for 90% of my work rotation for years. Once I get a decent patina built up I've never found them to be inconvenient in a pro setting. Personally I prefer the ease of touching up simple carbon knives over stainless but I'll admit, I've never used any particularly fancy stainless knives so I can't speak for how easy it is to touch up a Ginsan/AEB-L/R2 etc ect.
In busier places I used Chinese cleavers exclusively (vegetarian, meat and seafood) and a paring knife for in-hand prep. I just found them to be massively more efficient for bulk prep, especially vege. But now I'm working in a rural pub that's pretty rustic and quiet. Prep is pretty minimal to be honest, I'm using a 240 AS gyuto at the moment because it's what I have but it's overkill. If some ******* hadn't stole it at a previous job I'd be using a vintage 250 carbon Sabatier because I loved how it felt in hand and cutting chunky mirepoix is about as demanding as this place gets....
So to echo the previous points made, it really depends on the workload and the specifics of mise but to address the OP, I would go for a mono western handle without any bells and whistles: Misono EU, Sugimoto HM, Kikumori Nihonko or something of that ilk. All solid performers, I prefer yo handles, don't need to handle them gently and don't care if they look like s**t from thinning and scouring over the years cause they didn't look like much to begin with!
Cheers,
