Remote Office Infrastructure

TLDR: Wanting to move away from Ubiquiti. Thoughts on Mikrotik or PFSense (Netgate Appliances) for Small business routers?

Hello everybody - We are setting up a couple of remote offices in the spring and I'm reviewing our infrastructure decisions. In the past when we've setup remote offices, each office has been setup with EdgeRouter, EdgeSwitches, and Unifi Access Points. Due to issues with Ubiquiti (need I list everything), I want to switch away from Ubiquiti. Per very specific direction from our CEO, these remote offices need to be as independent as possible, we should not be involved in support, maintenance, updates, ect on a regular basis. so the more self-sustaining, the better.

Needs for the site are pretty limited. There are a few VLANs (~6), Less than 50 clients total (10-15 are wireless), and no site-to-site VPN / SD-WAN / Site Linking. Its not required, but I would like to be able to setup the ability to VPN into the site (not required, but would be nice for the rare time we need remote access for support). WAN Bandwidth utilization is ~50Mbps.

For reference, our Main Office has SonicWall Routers (most likely changing to Sophos in a year), Aruba Switches, and unifi APs (evaluating switching to either Aruba or Ruckus).

I'm still considering options, but right now I'm looking at a Sophos XG Firewall, Aruba Switches (either 2530 or InstantOn - The InstantOn Switch has a local, web based management interface which looks like it supports everything we need - we also get really good pricing on standard Aruba - so cost between them is pretty negligible), and Aruba APs (Either Standard APs in Instant mode or InstantOn APs)

I'm pretty confident on the switch and AP choice (open to feedback and other options I should consider), but I'm not sold on the router. Thoughts on Mikrotik (which I have never used) or PFSense (I've used the software but it has been several years and not since NetGate)? Are there other options I should consider? (specifically less than $400-$500)

TIA!
