As soon as you want this type of control, you'll end up having to design
your own beamer theme.  There are many themes out there: I suggest you
have a look at which one(s) come(s) close to what you want, copy it, and
change it accordingly.  But this will require a certain level of
LaTeX-fu unfortunately.

I've attached three files: an org file, the resulting PDF, and a very
minimal beamer theme that may be of use.  That theme puts an image (UCL
logo) at the bottom right of the slide and a page number at the bottom
left side.  Maybe you can modify this to your satisfaction.  Note the
naming of the beamer theme file and how you refer to it in the org file.

Two themes...?

For me, they are equivalent in any case: I do not like word processors
as they make me do the job of a typesetter and I'd rather worry about
content.  But I know what you mean.

Best of luck,
