If you live in a dense area with lots of APs and regularly get performance issues, power line networking will provide excellent ~400Mbps connections that are more than adequate for things like video calls unless your power cables are ancient or under-spec'd (some older houses can sometimes have lower gauge cables that may not perform as well and I imagine some knob and tube setups are not ideal for data transfer, either).

If you have newer clients that support it, Wifi 6E/7/802.11ax (or whatever it's called) uses the 6GHz spectrum that isn't as heavily used (yet). I've had good success with it in my multi-unit apartment condo (feels as clean as 5GHz did ~2010). Some higher end APs can also use multi-antenna beams that can help, too.
