I'll throw this out there, in case it helps the OP or anyone else.
I've had the Wahoo Roam, Bolt v.2, Garmin 530, and now Garmin 1040.
Wahoo computers are dead easy to configure and use, and probably provide enough data and options for 95% of cyclists. The Garmin 530 was (for me) a nightmare to configure, since it involved a gazillion button pushes and wading through umpteen menus, submenus, and sub-submenus, etc. The 1040, for all of its features and options, was relatively easy to configure as it has a touchscreen -- and the screen is very large. I just got the 1040 today, and got it all set up, complete with syncing up my sensors and configuring the Di2 buttons and Varia radar, in about 90 minutes. (Granted, a Wahoo can be set up in about 15 minutes, but it also does far less than the 1040.)
As for screens being too shiny, well, I don't even know how to respond to that. I've seen lots of reviews and complaints about cycling computers, but that's a new one.
