Personally, I don't want a huge hole in my phone and case that I'm never going to take advantage of. Wireless headphones with noise cancelling and such are far more convenient when outside than the open backs I use at my computer. The DAC in most desktops suck so I use a USB-C to 3.5mm anyways, makes it really easy to plug into my phone if I ever needed.
Just my opinion for my situation, but I would honestly rather buy the same phone without a headphone jack than one that did.
YouTube sound quality is poor, and 99% of your bandwidth being devoted to video is wasteful. Just use SoundCloud or something. Better yet revanced patched YT music or xmanager Spotify.
Edit: or better yet vimusic
