The issue with dongles is that you’ll have to find the correct aux dongle, some phones support analog passthrough, others require active dongles and so on

This is a pretty easy to overcome issue. There really isn’t a “and so on” here, there are only two types of adapters: active and passive. Nearly every new phone without a 3.5mm port needs an active adapter (check the spec sheet), which has the DAC in it.

This is fine, you were going to use a DAC regardless, the only difference is that it exists outside of your phone instead of soldered to the main board.

Probably best to buy from your phone manufacturer to ensure you’re getting a quality DAC, but I am not aware of any counterfeiting, supply, or quality issues for DACs. Quality Cirruslogic DACs are plentiful and cost manufacturers $1-3/piece, so even the AliExpress adapters are probably just fine.

I feel like people never complain that cases and screen protectors only work on one make/model of phone, but then they get upset that they have to figure out which of two adapters they need. You’re already dealing with a lot of device-exclusivity owning any smartphone, the headphone adapter seems like a trivial detail.
