Huawei or one of the other chinese phones. Build quality may be medium.
The Samsung S series tablets are their best build quality approaching the iPad. The A series may do what you want though. Seriously, a 9th or 10th generation ipad is the sweet spot for price/performance now. My old SS S7 is holding up without issues, but i only use wifi.
Qualcom radio chips are usually more robust than anyone else’s. I would definitely not chase wifi 7 or 6e. Wifi 6 is plenty and well established hardware and drivers. Wifi 7 just got formalized, so hardware and drivers will be chaotic for about another year. It will take many more years before you see access points widely available in commercial locations with wifi 7.
