Second this. I generally prefer properly wired connections, as wireless can never be as reliable. But there are scenarios.
We do that a lot at our theater in both directions, from wireless camera connections to free movable displays as a sink. Just now for a production we got a freely movable multi display platform, which gets its feed from two our Teradek bolt 4K lt 750. But it needs quite some experience and knowledge to navigate the caveats.
E.g. an issue to be aware of, can be the 5Ghz Wifi Networks in the same room. Especially if you go to have wireless (NDI) streams from a mobile device in the same frequency bands. As the Teradek doesn't recognize existing wifi networks, they just overpower them if on the same channel. This needs proper channel management, especially in Europe where most of the 5Ghz channels are DFS (radar saved) channels, leaving only two fixed channels for two wireless sets.
Therefore, if it doesn't need to be second hand for budged reasons, I very much recommend the 6Ghz versions.
For indoor usage, I can recommend the Mushroom Antennas as an upgrade. They are available for both Ghz variants and added connection stability for us big time. We don't have any experience with the internal antenna variant though.
