I wanna install Solus on a Laptop with an M.2 NVMe SSD. Is it recommendable to use a swap partition?
Also which kind of the file systems (ext4, btrfs & f2fs) is preferred?

thanks!

If you just started to use linux, just use ext4. Also regarding swap, generally it is useful to have it. In the installer, you have three options depending on your need: No Swap, Swap without hibernate, and Swap with hibernate. If you want to be able to hibernate/suspend/sleep choose the Swap with hibernate option.
