I’ll answer some questions like your initial points 1.1-7 and your questions 2.1-3
1.1-2: I don’t really know as I have a custom rom without a Google account anymore. But deactivating regularly just means this app and services bounding to it. So an alternative app will bring its own dependecies and can run as standalone.
1.3: You don’t have a sync frequence or a special time day time to sync, it is “now”. Only for calendar and contacs by davx you can set a sync period. Nevertheless you can set autosync on an update/upload.
1.4-5: There are the “phone” app like galleries, which will only search and show files (images) on the internal or sdcard storage. Even with a webdav connection you can’t find the images stored on nextcloud.
The nextcloud app aka nextcloud file storage app on the phone will show media stored in folders of the nextcloud.
Personally I would be happier to have a gallery with nextcloud link to show all images whereever they are. (maybe in the future).
On Desktops with a nextcloud storage as regular folder is no problem to access and store (rwx) files there.
1.6: Yes, this is right as the nextcloud app has access to the phone storage but a phone app has no knowledge about the nextcloud.
1.7: You have to look exactly. There is an upload for photos and one for movies. Even if both are in the same folder photos and movies are treatead as separate (and all other file formats will be not synced, even in these folders).
So, if you have in addition a folder for telegram, signal, whatsapp, you have to sync double, photos and movies. (Better would be just to upload a folder)
2.1: It depends on your settings. You have the option to keep files, just move files and move files + delete them.
2.2: As regular, the link between a folder on the phone and the virtual nextcloud folder is symbolic. Depending on your decision on 2.1 files on the cloud storage are independent from those of a local storage. You can compare it with a portable USB stick, copy the file, unplug and then you rename the original file keeps the file untouched on the USB stick.
2.3: Even here you can set the sync option. 2way means editing files will affects to “copy storage” file. on oneway is like for a media player, just listen to the music and don’t edit. So for 1way are 2 directions. 1 means just copy from the phone, no matter what happened on the cloud. 2 means copy from the cloud storage no matter what you have edited on the phone.
In addition, there is a problem with presenting images and movies. The phone gallery will show them in the direction of “created” meaning stored. So, your photo from year 2015 copied from your computer or cloud will be shown “today”.
In the nextcloud there is the chance to sort images by folder (date times), name and the original timestamp, so your 2015 photo will remain in 2015.
I always hate, sorting images from other people or as backup from an old phone into my DCIM/Camera folder and get these all shown as created as they are stored on the internal storage.
