Apps, themselves, don't take up much space. For instance, the Photos app is 0.04 GB. But I have a 135 GB Photos Library that the app manages. It's that data that takes up space. In "Settings>Apps>App Store" you can turn on "Offload Unused Apps" that will keep those app off your storage until you need them-- but that's just the app, not the data-- so it saves a little bit.
On my iPhone (not on my Mac) I use "Optimize Storage" for Photos, and that 135 GB of pictures actually takes up only 4.5 GB of space! That's because the original pictures are kept at iCloud.com, and only smaller version stay on my phone--small enough to make scrolling through them easy and quick. If I want to edit one, Photos grabs the full version from iCloud while I edit it.
For files that you may need to use, you can put them in iCloud Drive and Optimize that. Personally, all the files that I might need to refer to with my phone are smaller files, anyway, so Optimizing doesn't help me much.
The apps that take up space are ones that keep lots of data inside of them--like games! In Settings>General>iPhone Storage you can see how much space each App's data takes. Again, offloading may not do as much for you as deleting.
Ultimately, you just have to accept that having lots of stuff takes up lots of space (a truth about more than just phones!) Each time I get a new device, I get more storage on it than the last one. Like you, I'm tired of having to deal with it.
