Most recent Androids don’t have an audio jack either. Samsung dropped it from their flagship products back in 2020, and that change made it slowly throughout their line. The Google Pixels don’t have headphone jacks, the Moto Edge I use doesn’t have a headphone jack, etc.
Honestly, if you have a a phone made in the last few years that does have a headphone jack, I’m curious to know what kind.
FWIW, my last phone (until 3 weeks ago) was a OnePlus Nord N20. Absolutely stellar budget phone with a solid mid-range experience and features. It had a headphone jack AND an SD card slot, as well as dual SIM tray if that’s useful. I think it’s actually higher spec than the N30. You can still find those. OnePlus is pretty good about including a lot of that stuff, except on their flagship phones. Hope that’s helpful.
When I tried Sony’s 5 IV last year, it came with a headphone jack. Most of Sony’s lineup comes with it I believe.
I’ve got a Samsung A71 5G with a headphone jack - I recommend it highly except the lack of cases available for it. I shy away from non Samsung android solely due to https://apps.samsung.com/appquery/appDetail.as?appId=com.samsung.android.soundassistant
Which, without going to the trouble of rooting, let’s me tell apps to STFU regardless of their preferences.
The A71 came out in 2020, which was about when Samsung was phasing the jacks out. And they took them out of the S line first, which I always thought was weird - for a while, you had this feature that was present in their mid range phones, but completely absent in the more expensive flagships. They’re not the only ones that did that, of course, but it does seem kinda backwards.
My Moto also does per-app volume, and I agree, it’s pretty rad.
