A second concern was that installing foil-backed insulation is likely to

The second can be addressed with more access points, I could probably live
with worse mobile signal. So I should probably stop worrying about this and
go with the flow.

Yes foil in walls messes up inter room wifi and makes mobile coverage
strange but foil in ceilings is a different matter. You aren't receiving
signals in that direction except GPS, so your phone wont know where it
is when it's at home...

...and as far as solar radiation goes, what on earth are you talking
about? cosmic rays? Curiously the fact that its dark in a loft is a
fairly sure sign that all incoming solar radiation is stopped by the
roof...not by any insulation thereafter.
