If you have firefox mobile and ublock origin installed, open the addon settings and select my filters. Add the following (picked with ublock on desktop):

www.linkedin.com##.z-10.w-full.p-2.left-0.bottom-0.fixed.flex-col.flex.bg-color-background-container.rounded-t-\[20px\].text-left.promo-bottom-sheet__card
www.linkedin.com##.overlay

Then apply changes. You should no longer have that annoying banner at the bottom of the page

For me personally... I use VyOS in a VM running on a proxmox host (optiplex, SFF) with a 4-port NIC passthrough. This solves the issue of power for me, as the host has plenty of ram allowing me to run other services without needing an additional machine (although I do have one as a spare). VyOS doesn't currently have a GUI (one is in development), however, it has been very solid for me (also based on debian, which is nice).
