I believe that one may almost always cook something on YT and rely on
the possibility (it need not be a likelihood) that unexpected guests
will come and the cooked food will be used to serve them (Shema ikleu
orchim).

We learnt in daf yomi that that is not the reason nowadays. The 1st
Bi'ur Halocho in 527 (Al Yedie Eruv) goes through the 2 sides fo this
argument. The MB prefers one to be machmir as per RSM's reason (and
plenty Rishonim), yet agrees that the halocho is not so.

Thus, in priciple, one could cook all the way up to Shabbos.
