Yes, i think every mentioned point should be possible.
Wix-Studio is now the running Editor (if i would recommend it, like it is at moment? → no!)
Why? —> Take a look here…
Is it possible to create an interface behind the login?
What kind of interface? → But should be possible, when you create the login in CUSTOM-MODE (you also can use the Wix-Members-APP)
Is it possible to segment dynamic content into custom pages with custom filtering? I.e. separate blog from podcast etc. You can give more details about that?
But also looks to be possible.
You can get full control over the design of your LOGIN-SYSTEM.
But at the end you will need to be able to CODE in VELO-JS (using Wix-APIs) .
Thank you very much for your comment. I would add to the question about dynamic content. Does WIX work similarly to Strapi for example? Can I customize filtering by content? For example, assign a priority level to an article and filter accordingly?
I am also addressing the question of whether unique personified environments can be created on WIX behind a login? (different environment for each member, e.g. workshop, overview of his lectures).
Is it possible to connect WIX to other platforms where we could create dynamic content like Strapi?
If you want to use STRAPI for CMS purposes instead of Wix own CMS-System, you can use http-functions, wix-fetch, REST-API, or maybe even already a prepared NMP-Module for STRAPI to connect your Wix-Site with your wished 3.rd.-party provider.
Since you use STRAPI, there would be also maybe other providers for your purposes, like firebase? Not sure.

Environments, like MEMBER-PROFILE-PAGES ?
If so → yes.
You can do everything by code, if you know how.
Can I customize filtering by content?
You can generate own FILTERING-ENGINES in your own CUSTOM-MODE (code-mode).
