Re: fixed wireless, would that typically offer higher speeds than my current 5G home internet? Verizon advertises my plan as 25-75Mbps upload, but I never see that. I worry it’d be the same with any over the air service, but I haven’t really explored fixed wireless.
Due to how few units there are, your options are fairly limited unfortunately. You might try bonding together ATT, Verizon, and T-Mobile 5G Home service with a compatible router if there are no other options. It’ll cost ~$120-$140/month, but you’d have diversity that might improve the overall experience. When done natively vs using their 5G home devices, this is referred to as “cellular carrier aggregation.”
