What are the images in videos called? Looking for help with animations for Premiere.

I am trying to produce a few youtube videos for training for my company and i want to be able to present lists like recipes, and use arrows to point to things etc. Using the Essential Graphics I can really only find titles and "call outs". If I want to make a list, or graphic template that I can re-use with different text, is there a software that has all those templates in it already, or am I expected to make them with photoshop? I made a few using this program called Canva but when I imported them into Premiere they were formatted incorrectly.

I feel like there are numerous ways for me to accomplish what I'm doing, I would just like some guidance because with my history I'll choose the most difficult and time consuming method.
