I work from my van instead of "work from home" and do zoom calls all day long. I needed something fast, stable and reliable. I researched this extensively and ended up with this unit:
FTS Hennig bietet den 5G CPE Pro 2 Router von Huawei exklusiv mit 6 externen Antennenanschlüssen an - für besten 5G Empfang zu Hause & im Büro!

Not cheap, but I don't have any issues whatsoever and always get superb reception and bandwidth. I previously had a Netgear m5 5200 5G router and it was pathetic compared to this modified one from FTS Hennig. Using a 12v cable it pulls 2A/24 watts peak. I've got 4 wifi dashcams, and I recently setup a homekit setup with 2 homepod mini's to use for music or home theater as well. Never skips a beat and super fast wifi 6 with 5G speeds far above OEM internals with their antenna's!
