It's FOSS has an overview of 13 Raspberry Pi-like single board computers.
The Raspberry Pi Zero and the Raspberry Pi Zero W were added to the line up of Raspberry Pi's in the last few years. These ultra-small form-factor SBC's have been a big hit and continue to be a part of Raspberry Pi projects from the maker and DIY communities.
Due to the smaller form factor and the prices these boards are targeting, they have had to cut down on many features like a dedicated Ethernet port, slower processor (compared to their full-fledged cousins).
In an earlier article, we listed the best alternatives to Raspberry Pi. In this one, I'll list some alternatives to Raspberry Pi Zero and Zero W.

You probably want something more like ODROID-H2+ [hardkernel.com] or the ODYSSEY [seeedstudio.com], but you still aren't going to get the number of USB ports you want. The H2+ has two SO-DIMM slots for up to 32 GiB of RAM.
The way I see it, you want two different form factors. Something smaller like the Raspberry Pi 4B or the LarkBox [notebookcheck.net] should be what gets a "boat load of sensors". Fits in palm = portable. Either one has some room for a tiny SSD (RPi doesn't yet but they are considering adding some connector in a future version).
Then you want a few sizes up. Larger than H2+ or ODYSSEY, but smaller than most desktops. Maybe Mini-ITX? It will be overpriced, and you still might not find 8 USB ports on it.

USB hubs should definitely be used to connect to 8 RTL-SDRs. Connected to USB 3.1 Gen 2 or faster ports if necessary.
