Wireless pin headers would certainly make this design easier

Okay lazyweb, what’s a good connector to join two PCBs together in a sandwich with a gap in between? Mechanical design isn’t finalized yet, but both boards shouldn’t move relative to each other once fixed in place. Gap between two boards will be minimum 5mm or so because they are both double-sided. Minimum 8 connections, more would be nice to have.
Last time I used the common and cheap 2.54mm pitch pin headers and sockets, but these might be too big for this time now that I’ve crammed an entire antenna on the board.
Maybe 1.27mm pitch pin headers and socket?
Maybe a pair of FFC? I’d worry about the durability of the connecting cable.
Maybe a pair of Molex PicoBlade or JST SH? I’d worry about the additional cost for the cables.
What else do #electronics folks use for small but relatively tall board to board connections that can double as mechanical supports?
@jpm I've had some luck with mezzanine connectors for a prototype project I was working on
@jpm Go through https://connectorbook.com/identification.html?N=&n=board_to_board_conn and select something that looks ok, e.g. Panasonic P5KS. You can also use Mated Stacking Heights filter on Digikey in Connectors, Interconnects → Rectangular Connectors → Arrays, Edge Type, Mezzanine (Board to Board) category.
@owiecc thanks for the tip on stacked height on DigiKey
@jpm the solution you are looking for is BergStak, my guy: https://www.amphenol-cs.com/product-series/bergstak-lite-0-80mm.html
@ThermiteBeGiants way too big, the entire PCB is 26 x 26mm
@jpm vertical USB-C, full yolo
