Putting the smart devices on the edge allows for a much-simplified core topology.
Either way, I was doing research on FPGA-based hardware a couple of weeks ago and came across this which may tick all the boxes. https://ethernitynet.com/products/enet-network-appliances/uep-60/ I do not know the vendor personally and have not worked on their hardware, so your mileage may vary.

Caution: This is an external email and may be malicious. Please take care when clicking links or opening attachments. I think you’re probably overthinking this a bit. Why do you need to extend your vxlan/evpn to the customer premise? There are a number of 1G/10G even 100G CPE demarc devices out there that push/pop tags, even q-in-q, or 802.1ad. Assuming you have some type of aggregation node you bring these back to, tie those tags to the appropriate EVPN instance at the aggregation point. Don’t extend anything but a management tag and an S-tag essentially to the device at the customer premise. You can even put that management tagged vlan in it’s own L3 segment, or a larger L3 network and impose security. This way you’re not exposing your whole service infrastructure to a bad actor that might unplug your cpe device and plug into your network directly.

Hello, all. I’m having difficulty finding vendors, never mind products, that fit my need. We have a small but growing number of L2 (bridged) customers that have diverse fiber paths available, and, naturally, want to make use of them. We have a solution for this: we extend the edge of our EVPN VXLAN fabric right to the customer premise. The customer-prem device needs 4x10G SFP+ cages (2 redundant paths, plus LAG to customer), and the switches we currently use, Arista 7020Rs, are quite expensive if I’m deploying one one per customer. (Nice switches, but overkill here – I don’t need 40/100G, and I don’t need 24 SFP+ ports. And they still take forever to ship.) We use RFC7438 §6.3 “vlan-aware-bundle” mode, not §6.1 “vlan-based” mode, which limits our choices somewhat. I might be willing to entertain spinning up a separate VXLAN mesh using RFC7438 §6.1 (“vlan-based”) and static VTEPs if it saves me a lot of pain. However, I’m having trouble finding small & cheaper 1U (or even desktop/wallmount) devices that have 4 SFP+ cages, and can do VXLAN, in the first place. Who even makes CPE gear with SFP+ ports? (Other than Mikrotik CRS309-1G-8S+IN / CRS317-1G-16S+RM, which are nice, but our policy requires vendor support contracts, so… no-go.) Vendors? Model#s, if you happen to know any? Reply here or privately, whatever floats your boat – any pointers appreciated!
