What is your point--or question? Form elements are complex. I'm not familiar with cypress. Puppeteer has worked fine for my needs. If the thesis is simply that using web components is a chore, well, welcome to frontend work. It has always been a chore in one way or another. Web components are the first time I can say--for my own professional experience--it was less so than previously. Generally a superior experience to all of: React, Angular, Backbone, jQuery, etc. Maybe you just need to hire me? I couldn't say without more detail.
