Depends, but usually not. A Campy 10 speed + a Shimano derailer will index cleanly with a Shimano 8 speed cassette. Other combos are theoretically not clean matches, but some people consider them to run well enough to be useful anyhow.
If you do a net search for "shimergo" you'll find a link to an UK site listing possible combos.

SRAM MTB groupsets typically have a simpler hierarchy with fewer options compared to Shimano groupsets. SRAM uses a 1x (single chainring) system, while Shimano offers both 1x and 2x (double chainring) options. SRAM's top-tier groupsets are XX1 and X01, while Shimano's top-tier groupsets are XTR and XT. SRAM groupsets are known for their lightweight and precise shifting, while Shimano groupsets are praised for their durability and smooth performance.
The hierarchy of Shimano MTB groupsets starts with the entry-level groupsets like Tourney and Altus, followed by mid-range groupsets like Deore and SLX, and then higher-end groupsets like XT and XTR at the top.

Strictly speaking Mavic doesn't make freewheels, which is the name for an integrated unit holding BOTH the sprockets and the one-way clutch mechanism. Mavic makes freehub bodies, and they make them for both Shimano and Campagnolo sprocket clusters(AKA cassettes). Which means that if you have a Mavic wheel/hub you can set it up either for Shimano or another brand, by using the appropriate bits. Although there are a few workarounds and fixes, you'll usually get more reliable results if your shifters match both your cassette and your derailer.
Some of the best gravel bike shifters available on the market today include the Shimano GRX series, SRAM Force eTap AXS, and Campagnolo Ekar. These shifters are known for their precision, durability, and smooth shifting performance, making them popular choices among cyclists.
