Isn't nostr still an append-only solution?

Then clients and relays SHOULD act as if the referenced event is deleted. This is different than MUST, probably because there’s no way to guarantee it happens. It’s also possible the delete event doesn’t make it to everywhere that received the initial event.

Only if someone cares enough about your social media to be watching for deletions, which I'd imagine is pretty rare. If no one's watching now, now is the right time to delete something.

I think it's important not to overstate that effect, as there are lots of scenarios where deletion will not draw more attention to something. For instance: you're a rando deleting something that's not interesting, not currently being observed, or something no one will notice when it's gone.
The trope namer got hit by it because 1) she's a celebrity, and 2) removal would result in a noticeable gap.
It would, if someone were looking in detail, but that isn't what the Streisand Effect is. That effect is the demand to stop/remove something that draws attention to it, not the actual removal (if it is indeed removed at all).
If the photo of her property had been quietly removed by the photographer I and most others would likely never know anything about it, much like you and most of the rest of the world wouldn't know I deleted a post on my blog that was so full of embarrassing typos that I couldn't be bothered to correct it. I know about it because of the heavy-handed demand that it be removed from that collection.
A better way to think about it is: do you have good reason to think someone is actively watching you or will go through the effort to collate your social media posts against some archive (that will be incomplete unless you're an active target)? If you don't, delete away.
If you're still concerned, delete some old stuff randomly to distract from the stuff you really want to delete.

Those can't even scrape everything people actually want to keep, let alone comprehensively scrape every social media post from everyone. There are huge gaps.
I actually was peripherally involved in some volunteer efforts to archive a bunch of stuff around the Hong Kong protests and the Afghanistan withdrawal. IIRC, they didn't even try to scrape Facebook posts (because FB was doing so much to thwart scraping, and there may have even been problems with Twitter). There are well-developed tools for YouTube, through.
