Drupal 8.x

Webform contact form default ones email field validations not working if some one type wasojofy@mailinator without .com it still accepting and submitting the form

Can someone help me understand how or what is the best approach for upgrading a drupal site from 8.7.x to 8.9.x / 9.x. (Community recommended to upgrade to 8.9.x first and then to 9.x)

How can a non profit organisation plan the frequent upgrades coming up?

We have about 50 contrib modules to be updated, Also to upgrade to 9.x, 40% of existing contrib modules are not available.

Using Drupal 8.9.3.

Steps:

I am using the group module in my site then installed webform_node and group_webform to be able to add my webform submissions to a group, but I want to add some submissions to their groups programmatically like I am doing with simple nodes.

In hook_ENTITY_TYPE_insert() I add nodes to their group, I want to do the same with webform but not sure if it can be simple since it needed integration module to work with group module.

I have some nodes that aren't visible to the non-identified user because it is specified in the view that I´ve created.

However, If you know the path of the node , it´s possible to access to this. I would like that a non-identified user can't see the node although he has the path.
