Edpuzzle is a great resource that allows you to make assignments using videos (you can create your own or use existing one from their bank). I find it most useful when I feel like I've been using too much text, especially if there is a cool video about a topic, and I want to have students interact with a different media. It can be synced with google classroom, and you are able to make quizzes and see student scores and viewing progress on videos.
Edulastic is my go-to digital assessment creation tool. I like to use edulastic for quick formative, and sometimes summative assessments. There are a variety of question types you can create, and question creation tool can be tailored to the subject you teach. There is also a bank of questions you can borrow from if you're looking for quick assessment questions, which you can modify as you see fit. Of course, the best part of this tool is that you can sync it up to google classroom to help make grading a bit more efficient.
I like to use quizzizz for end of topic review sessions. I've found that it is a bit more interactive than quizlet, and can be used in homewok mode (meaning students can retake the quiz as many times as they see fit within the test window) or live mode where students complete the quiz at a similar pace.
