What aspect ratio...

[Humanity]

.. are regular big name movies made these days shown in at theatres?

I mean theatres specifically, not your regular Blu-Ray home release.

I have done some web searches but not found any answer.

It varies, and that is before we get to the oddities like the hateful eight and throwback films where people do things, or change during the film to signify a different era. You might also notice trends between regions -- a lot of UK, Australian, some European and BBC productions are noted for using some different approaches (often 1.56:1 or 14:9) to US based films (1.85:1 or 2.35:1, among others).
CinemaScope was once a term people used but as far as practical numbers it is more of a range of them these days. We also have the 4k debate to unpack -- there is/was some disagreement between film videographers and PC makers where the PC types stuck together a bunch of 16:9 monitors and film makers did another thing.

If you really care then IMDB will usually list the aspect ratios under the "Technical Specs" section. Pick a bunch of popular films of the last year(s) (Oscars might be a start https://www.imdb.com/search/title/?...picture_winners&sort=year,desc&ref_=nv_ch_osc ) and see what goes.
