What’s the best VPN for small business remote workers?

I run a marketing agency with six employees, all remote, and I’m starting to realize we probably need something more serious than everyone just doing their own thing security wise you know

Right now we have client data scattered across various personal devices, people connecting from coffee shops without any protection, and I just found out one of my team members has been using the same password for basically everything including our shared drives which honestly scared me a bit

I’m not looking for enterprise level stuff with dedicated IT requirements because we definitely don’t have the budget or expertise for that, just something manageable that gives me some peace of mind, ideally one solution I can deploy to everyone without needing a computer science degree to set up

Main concerns are making sure client data stays protected when people are on public wifi, having some kind of basic password management so the password123 situation doesn’t happen again, and maybe monitoring for breaches since we handle some sensitive marketing data, is that too much to ask for a few hundred a year for the whole team or am I dreaming here
