KVM? Virt-Manager? It might take an hour to learn virt-manager and some of its quirks, but it absolutely can do everything you request here, I do so very regularly.
If you want a low-maintenance version, you could just snag someone's NixOS config - you'd have an easy to reproduce environment that just ensures virt-manager and a really light-weight window manager are installed and then you're done.
Virt-Manager does shared directories (9p anyway; there's no UI for virtio-fs, but you can still use it by editting XML). It handles USB2 and USB3 forwarding. It does snapshots, it does clones, you can even leverage Linux filesystems to do far fancier things than possible on HyperV hosts. Etc. (Plus KVM won't trash your plain ole EXT4 partitions like countless people keep reporting under HyperV [and I've personally experienced twice]). It can even do graphics accceleration/virtualization for Linux guests.
Virt-Manager is so under-known and under-appreciated, but then again, it's got its rough-edges. With some polish there is really no reason to ever mess with VBox under Linux.
