Favourite set would be the BVM 20F1E when it comes to 240p. Sadly not that many buttons since they are all on the remote. Here one could think of either putting the remote on the top of the screen or make a version of it with the suitable mount kit. Otherwise there is the PVM 20L4 or 20L5 (the latter never released here in Germany) that has the controls on the left and the right side of the screen in the forms of buttons that light up when activated. Could be a cool eye candy for a theme.
A similar glow up button control can be fond on the PVM2950 which is a set that looks more like a consumer set.
For variation there are also the MD versions of PVMs which had white / grey housings which would also look nice as a bezel.
Another PVM that has lots of knobs and buttons, is shadow mask and therefore has horizontal and vertical curvature is the Ikegami TM20-17R. The current bezels reminded me of it since it has a very deep bezel.
Also maybe some love can be given to the tally light on the top of the bezels that can light up when the screen is in use.
My personal go to set is the Bang and Olufsen Beocenter 1 since I love the design and the image quality is very good for a consumer set. There is also the Bang and Olufsen MX8000 that is a 29" with a very simple design language.
There is a huge community around CRTs on Reddit and FB. Maybe there could be some collaboration between these enthusiasts that know every detail about their cathode ray babies although many of them would call emulation, shaders and bezels Blasphemy
