Yep. The overwhelming majority of IDEs have support for making templates/snippets.

VScode/VScodium has a very robust snippet system where you can set parts as "fill in the blank" that you can tab between, with optional drop down menus for choices. You can even link different "fill in" sections so you can do stuff like type in an argument name and have it propagate that same name through multiple places in your snippet.

If that's too much, how the fuck can any dev (or even someone hacking together scripts) survive without at least one file of common shit they made before that they can copy paste from? I really feel like that's bare minimum.

Either it's boilerplate you can already copy from somewhere else (documentation or previous work), or it's something you should probably review (at least briefly) and make into a template or snippet you can copy and paste later. That's part of the magic of programming: you get to build your own toolbox over time.
