Ok, then I'll do a list of the
settlemods settlements. Use the standalone version with individual ESPs,
DO NOT EVER EVER INSTALL THE FULL VERSION!
In general, most, if not all of those have reappearing items or objects like beds. This is a minor issue IMO, and can be fixed by manually disabling them using the console. Also, this is a list of my experiences, results may vary. And lastly, as these mods are abandoned, use at your own risk!
If there is a newer mod which does the same location (MrCJohn posted Fairline Hill and Natick, for example), better use those instead.
Also, Scrap Everything is probably a must, since some objects aren't scrappable otherwise.
Mostly Functional/"worksforme":
Natick Power Plant
Fairline Hill Estates: The player home interior is somewhat buggy, but the settlement itself seems to work. If you are using my Immersive Teleporation, teleporters won't work in the interior because of it's bugginess.
Fiddler's Green
Huntress Island
Norwood Depot
Eden Meadows Cinemas
Ryder Rentals: definitely has respawning items
Rocky Narrows: has respawning items and some other objects
Nuka Island
Buggy/Stay away:
Evan's Way: something's off about the Location. Settlement Management Software actually reports two locations of this name. One of them is the actual settlement, while the other one seems to be where you are actually in. That is, things which try to get workshop by location will always report an empty settlement if used in there.
Easy City Downs: not only does this completely destroy a vanilla location (and isn't even thorough about it), the resulting settlement has no functional map marker, and no settlers can be sent there.
Westing Park: Destroys another vanilla location, but the amusement park it puts there is actually kinda neat. However, the 2 (or were it 3?) interior cells there have some major fuckup, which leads to any settlers you try to send to the settlement actually appear in these cells. Also, suffers from major respawning items, including quest items (which have been moved from the vanilla location)
Glowtopia: has no functional map marker. Also, has a loaddoor to actually enter it, settlers have problems with it. I think I actually could settlers there, but I'm not certain.
Rad-B-Gone Island: No functional map marker. I think I actually could settlers there, but I'm not certain.
Other settlement mods:
Relay Site Alpha: A glowing sea settlement. Has the minor issue that the workshop border is visible before you activate the workbench for the first time.
"Kenmore" Subway Station: an interior settlement next to Hangman's Alley. Might have some minor visual glitches, but works well enough for me. I also renamed it to Fens Way for myself, because that's what it says on the entrance.
