Lauda89 here is my current list. Bear in mind that this was NOT the case previously. I've spent a lot of time adjusting to screens in cars because I love cars. And my symptoms in general are very well managed now - my sensitivity to LED lighting in stores has gone down, and I can visit people's homes with LED lights and generally not have a problem.
Subaru models other than BRZ and WRX: Fine. It took me a little bit to get used to the infotainment screens, but once I did it was fine. I can get into any modern Subaru and be fine with no adjustment period.
Subaru WRX (my current car): higher flicker rate on the gauges means that adjusting is harder. Higher brightness on the infotainment also, even though both look just like other Subaru models. I can adust to this but it takes some time. My current car took me a couple weeks to adjust to fully but now I have no pain or difficulty.
Subaru BRZ: This is a toyota screen and I haven't used it yet, so I can't say for certainty, but likely it's ok because Toyota is ok:
Toyota modern screens (ex: RAV4 Prime) - no problem. The infotainment is ok as are the gauges.
Volvo Screens: This took a little adjustment but now I'm ok with them.
BMW iDrive 8.x: a real problem. I have to force my eyes to focus on these screens. I don't know what it is about them that is so hard to look at, but after a test drive of such a vehicle I will have severe vision problems. We test-drove a few BMW's one day and by lunchtime I literally could not read the menu at the restaurant!
BMW iDrive 7: Much better. Not perfect, but I'm confident I could accomodate. I drove an iDrive7-equipped 530e across Ireland for a weekend, and while I didn't love the infotainment display the main gauges were fine... and I had no eyestrain that persisted past the drive. I drove multiple hours in one go and had no issues.
Mercedes Benz flat gauge displays: USUALLY surprisingly ok. I drove an A-class in 2022 for a week, and had zero problems which surprised me greatly. I recently test drove an AMG CLA, and DID have a little accomodation trouble with the display. I then drove a C class, and was fine with both the gauges and the HUGE low-mounted infotainment screen.
Alfa Romeo: I got a little eyestrain from their analogue gauges (which your friend's Stelvio had) but it was the kind that would quickly pass for me. I am going to test drive an Alfa Romeo with the new modern digital cluster this week, so stay tuned for that report.
Honda/Acura: infotainment is fine, albeit the touch screens (half the lineup has trackpads and no touch) is a little harder, likely due to multiple panes of glass between the display and my eyes. Their gauges, however, were a bit hard to focus on... much like the BMW ones.
Mazda: no problems with gauges or infotainment, however the last time I drove a Mazda it was a 2022 model with full analogue gauges. But their infotainment was no problem.
Audi/Vw 2021 and older (analogue gauges, small infotainment): Zero problems.
Audi/VW 2022 era (1st gen digital cockpit): GODAWFUL. Instant eyestrain.
Modern Audi/VW (2024-2025 models): Unknown, on my test drive list.
Ford Digital Displays, mid-201x. I daily drove a 2014 Fusion Hybrid with the digital clusters for several years. During that time I had "tired eyes" after driving. Not to the point of actual strain, but it did contribute to road weariness and driving hypnosis. I would often cover the digital clusters to give my eyes a break. The infotainment was no problem. I tried a last-production-year Fusion (2021/2022) and it was actually surprisingly fine. But I didn't drive it for an hour so I couldn't say.
At this point, I'm actively auditioning cars and I am taking extended test drives. This week alone I drove:
Acura TLX: Total drive time 30 minutes. As indicated above, the infotainment was 100% fine. The main gauges were hard to focus on, but not impossible, and I got no eyestrain from the drive. I have confidence it could have been beneficial.
Mercedes/AMG CLA35: Total drive time 40 minutes. Not a ton of eye fatigue, but the main gauge cluster was a bit hard to read at times.
Mercedes C300: Total drive time 15 minutes. Right after the AMG. Didn't have any problems. Even with the giant infotainment screen.
BMW M440i 2022 (w/iDrive 7): Main screen fine. Infotainment a bit rough. My eyes were already a bit tired, and seemed just fine after the drive, but after a couple hours they got VERY tired. I think maybe I can't handle these as well as I thought. But I also think it's the infotainment that's the problem, not the main gauges.
I'll update this as I drive cars.
