Here in New Zealand 4G has proved to work surprisely well for FWA (Fixed Wireless Access). I think the important thing is that the providers need to be very strict at limiting the number of customers they sell to. Here, the providers will proactively stop selling new FWA connection in a certain area the tower sector serving that area is getting close to capacity limits. They'll also check where the customer is located and ensure they can actually provide a decent service. This check is done automatically off coverage and capacity data.
Most of the major FWA providers are mobile phone carriers, so both mobile and FWA customers actually use the same tower/spectrum/etc so the general increase in demand (especially from mobile given they can't stop selling new mobile servcies) sometimes results in a good service in Year 1 degrading to poorer service in subsquent years. However the carriers can easily resolve that by adding more 4G carriers, deploying 5G, and even building new cell sites (which kills two birds with one stone -- better coverage for mobile users and more capacity for FWA users).
When FWA first came out I confess that I thought it was a silly idea until my eldery mother accepted an incentive from her provider (cheaper monthly fee) if she moved onto FWA (from ADSL previously). She's zero complaints. And sure enough it works well for a low-end user -- emails, Facebook, WhatsApp, Netflix, YouTube, etc all work just as good on FWA as it does on fibre/DSL/Cable/etc. She happens to be close enough to the tower and that tower has also been upgraded and has heaps of 4G carriers so the service is consisently good.
YMMV but when done well, 4G/5G FWA is a great option for low-end users.
