Personally, I use a PC fit bike with two different cranksets (155mm-185mm & 140mm-170mm), a vertical laser, and my eyeballs. I did a few hundred fits with the Retul Vantage a few years ago and decided the juice wasn't worth the squeeze. I found it to be a good tool to train and confirm my eyeballs, but not something I needed to be ongoing. I use my phone to shoot video during the fit, and freeze frame and slow mo as needed to double check or take a closer look at certain things.

The bike has a Kinetic Smart Controller and I use the Rouvy app and a basic flat recovery ride to control resistance during my fits.

I use about 4 tri saddles and 6 road saddles and that gets me through 90% of my fits. I use the Profile Design fitting bar for my road fits and a basic Profile set up for my tri fits. I dont have any of the new full forearm rests. I dont have any monitors on the wall for riders to see live video or view their pedaling mechanics. Nothing against them, but I have never used them, never felt the need for them, and suspect they could distract and detract more than assist.

I have a really simple set up in the back corner of an accommodating bike shop, and sometimes I see the fancier set ups and get a bit jealous, but then I do my work and I never feel lacking in anything. I still use a (highly modified) version of the FIST fit sheet from 2012. I give a paper copy, a PDF copy, and generally 1-3 :05 video clips, including "before and afters" if possible.

I've fitted for going on 15 years, over 4000 fits now, mostly and currently in Richmond Virginia. Charging $350 with 1 follow up included. Just upped my prices significantly in the last 6 months.
