Its not a choice of which is "better".
This is not a direct apple-to-apple comparison.

One is wireless, another is fibre. Speed and latency, of course fibre beats hands down, regardless of condition (no 4g/5g congestion).
For plenty of users using simultenously, fibre is better. 4G/5G wireless can also support but not recomended for multiple users using heavy downloading/streaming simultaenously
For mobility, wireless 5G or 4G can bring to anywhere, office or another home.

For me, I prefer wireless. can bring anywhere.
My parents have Unifi fibre, but only use for very light usage. Wasting.
