Well yeah.  EOIP can set any arbitrary MTU in the tunnel and will deal with
fragmentation at the top layer.  
We do VPLS also.  We can certainly also do GRE, or any number of other
methods.

The issue isn't having a technology to use, it's about having a way to
present the NOC with a pane of glass to see and troubleshoot those
connections without having to be router experts.  At least if they can see
that it's up or down and maybe run a test of some kind and then only
escalate to engineering if there's an issue.

Ethernet over MPLS and/or VxLAN come to mind.

EVPN is built for this type of signalling.

VPLS is a little older, but can do it as well.

Bridging ZeroTier to an ethernet interface will work too.
In fact, I've done it with MikroTik running ROS7.  The nice part with
ZeroTier is that it will present an MTU of 2800, and deal with
fragmentation/reassembly "over the Internet."

I will caution, that whenever you feel like stretching L2 between sites,
there is generally a better solution available.
