Sorry to be late to the party, posted a comment to a comment much earlier; Krunner on Debian or practically anywhere else is Recoll

For what you call ‘MacOS like search’ I’d recommand Recoll, working on any OS (and perfectly on my Debian install, for years on) : really can find ANY text string inside any document, from almost any app (e. g. Joplin, that I’d bet nobody heard of here), also including e. g. words within attachments within zipped backup email databases, pictures located on unpermanent backup volumes etc.
Regularly updated, that the one thing that definitely had me ‘finally forgetting’ MacOSX.

For public transport nly (I mean, not live traffic) you have the open source Transportr on Android at least (on F-Droid for instance)

immutable. So, no, sorry.

I don’t know what exactly is blocked worldwde, but in the frenche Wikipedia here, while the description is short, it’s here and extremely explicit:

[ANI] est pointée comme une « fabrique de fake news », un canal de désinformation proche du gouvernement indien4, dont les articles citent pour décrédibiliser les rivaux du pays de prétendus experts inventés de toutes pièces in other words, ‘{the ANI news agency] is considered a fake news factory and a deinformation channel close to the government whose papers use to quote invented fake experts to de-credibilize rival countries’ Couldn’t be clearer (and unbanned)…

same with my old Lenovo P53 (for years) -I needed adding some packages though, but that was so long ago…
