I use an hama 00200117 with my FP4. It has 2 USB-A 2.0, one USB-A 3.2 and an USB-C PD Ports. It costs about 30 Euro.
I run an archlinux in termux with proot-distro and the enlightenment desktop on top with tigervnc. As VNC Client i use AVNC. So i have a better Desktop experience than with the Android UI.
