Lightbox dependability for essential functions

My question is about dependability of lightboxes. As a “best practice,” should lightboxes be avoided in favor of a standard web page for essential functions–in particular, for order forms–for dependability reasons? Perhaps, say, due to problems with browser compatibility or user privacy settings in their browser that may block or impair lightbox functionality?
Thanks for any recommendations from your experience.

Depending on which Wix-Editor you are working on.

Known issues regarding the Lighboxes:

On ordinary Wix-Edditor: Bad RESPONSIVENES!
Lighbox can be displayed in wrong resolution (size).

How it behaves in Editor-X or Wix-Studio → not tested.

Thank you for this caution. I appreciate you taking time to respond!
