I suspect they are data, voice, or video jacks. Found in a conference room for a building from the 80s-90s. It’s the same wall as the TV. There’s also other existing RJ45 Cat 5 ports.

They match the style of proprietary A/V control system ports used in 1990s conference rooms, Projector control interfaces, Crestron / AMX / Extron wall plates, RS-232 or RS-485 wiring inside custom housings.
They were used to connect Projector control panels, Motorized screens, Audio/video switchers, Touch panels, Old teleconferencing gear.
Absolutely look like custom bullshit connectors used on custom boxes from the 80s.
This is a great answer exceeding my expectations. Thank you!
No problem, being old has to have had some benefits lol. This was my shot.
OP said it was in a conference room. Good catch!
