On Monday I have to travel by car to London along the M40 and then get
to get to Saint Paul's by 1000. (I normally use Chiltern trains or
drive down the M1 and park at Stanmore but this time logistics are
unfortunately dictating otherwise.)

When I previously used to do this I used to Park at Perivale and take
the Central Line. However, I've not done this for a long time and
recall someone here saying that Perivale's station car par is now full
very early.

Anyone have any other ideas about any West London Central Line stations
with reasonable parking?

Not the Central Line, but I always used to park at Ickenham, which is a
few minutes drive north of Hillingdon (whose carpark I found filled up
rather sooner).
