I have unsuccessfully tried to control the font size of \footcite with \renewcommand{\bibfont}{\tiny}? Is there any other way?

From info latex:
\fontsize{size}{skip}
Set font size. The first parameter is the font size to switch to; the second is the\baselineskipto use. The unit of both parameters defaults to pt. A rule of thumb is that the baselineskip should be 1.2 times the font size.
As @frabjous noted, you'll need to add \selectfont afterwards to make it kick in.
As you don't use footnotes for anything else, you can modify \@makefnmark (this is what \insertfootnotemark calls)

Changing the fontsize with
\citesetupwill affect all citations, not only those in footnotes. Simply redefining\footnotesizeto\scriptsizewouldn't be advisable forarticleorbookdocuments because the standard\footnotesizecommand includes settings for the vertical spacing of lists and displayed equations, while\scriptsizedoesn't. This, on the other hand, shouldn't be of concern in abeamerdocument. So I'd say thatis the way to go.
EDIT: I had forgotten about the
biblatexconditional\iffootnote. I still think that redefining\footnotesizeis preferable because it will also affect non-citation footnotes.
