That is a wonderful website, I wonder if it is in any sense "official"
because I thought the ATOC considered fare information "commercial" and
so could not be released? But one defect (for my point of view) it
doesn't have fares to "London Thameslink" so it doesn't show the
cheapest fare from say Luton to London Bridge. I can't see any trace
of an email address on the site to point that out to them.

Using purely Oyster it is so simple you barely have to think about it.
Combining ticket media is much more involved as is the disparity
between cash and PAYG rates as evidenced by the above.

True, so for the journey I am planning (Luton to Amersham via London)
I'll have to price up using a Luton to London Thameslink plus an Oyster
card return from zone 1 to Amersham, and compare that with the Z1-6
Travelcard plus excess, and with getting a Z1-9 Travelcard (if they
still exist) starting from anywhere along my route.
