I'm not a purist when it comes to vintage hardware so I always try and keep my eyes open for new hardware projects for use with old equipment. I assume everyone here knows about the ZuluSCSI/BlueSCSI/PiSCSI. I've also found:
https://github.com/delan/usb3sun
Use USB keyboards/mice with old Suns. I've played around with mine a bit and it seems to work well

A new SBUS card! It interfaces with a FPGA board to allow for HDMI output. The required FPGA board is quite expensive...
https://github.com/mdehling/tgx-plus-vesa-mod
New EPROM for TGX+
https://github.com/halfmanhalftaco/sunboot
Sunboot - easy netbooting
Various 3D printed adapters - easier than tracking down disk trays for example
