IME, MPLS is a good use-case here. If you are going to use the same /24
(or whatever prefix applies to you) across multiple locations, you will
need some kind of overlay. Be it IP-in-IP, GRE, MPLS (l2vpn's or
l3vpn's) or plain old Ethernet, you will need something.

MPLS makes a lot of sense to me. It's native in hardware, upper-layer
agnostic, mature, and reasonably affordable even at low scale. While I
would not say MPLS is simple from a "complexity in your network"
standpoint, it does provide a notable amount of simplicity when you're
looking for an overlay that is transparent to all manner of Layer 2 and
Layer 3 applications that a packet-based network needs to transport.
