> some manner of universal connector Sounds like you want usb type c! In addition to Audio Adapter Accessory Mode which allows it to drive a couple pins with analog audio exactly like the 3.5mm jacks (and therefore enabling completely passive adapters to support devices with 3.5mm jacks), usb type c also supports charging, high speed data, and video. That's a lot more universal than some silly jack that can only support audio. Unfortunately it looks like at least the fairphone 4 didn't support Audio Adapter Accessory Mode and I haven't found information on whether the fairphone 5 supports it. Definitely a mark against the company if they don't support Audio Adapter Accessory Mode.
