General Returning to IOS Modding (Helpful Tips Appreciated)

[Game Sphere 15]

Hello, everyone!

It's been quite some time since I have dabbled in Jailbreaks, Non-Jailbreak IOS App Mods, and everything in-between. I'm talking sometime around 2016 would be the last time I had a jailbroken device (untethered).
I would love to refresh my knowledge in hopes of doing some "Non-Jailbroken" IOS App Mods, as well as how the landscape has changed over the years for Jailbroken Devices (Is Untethered still required?)
I currently get my "Non-Jailbroken" IOS mods from the IOSGods Web App, though I would like to learn how to update apps that are requiring of it, instead of waiting for someone to do so.

I suppose my main questions are:

• What program(s) are needed now in order to push my own updates?
• Is an "Untethered Jailbreak" still something that people use? If not, how come?
• Am I walking myself into something that I am too far out-of-date with?

I do have an Apple Developer Account, so signing apps shouldn't be an issue.
If there are any useful or helpful tutorials out there that I could dive into, I would love to do so. It's been quite some time since I have done anything like this, though I do have previous experience (though it be a long time ago) so I'm not diving into this *completely* blind.
I appreciate any tips, points in the right direction, or information into what I need to refresh myself on in order to release these kinds of "Non-Jailbroken" mods.

I have:

• Desktop at home
• M2 Macbook
• Iphone 14Pro Max (IOS 17.4.1)

I appreciate any replies!

(If this is the wrong place for this post, please let me know!)

Edit:

I am looking at the Tutorials section as well, there are lots of great looking posts, though the reason I posted here is so that I could get some pointers on which tutorial(s) I should look at so that I am not wasting my time while trying to learn this stuff again!
