I think the correct approach is to have PAYG as far as the terminal
point on the inner suburban 'all stations' services. So far, Watford
Junction meets that criterion and spots like Slough, St. Albans,
Welwyn Garden City, Hertford (maybe both ways), Shenfield, Grays,
Dartford, Sevenoaks, Windsor (maybe both ways again) might be a good
idea. Of course, on some routes, there are no inner-suburban only
services. On some routes, such as Southern, the inner suburban
services already only run in the zones and so nothing would need to be
done.

Ah but what is an "inner suburban all stations" service? Southern have all
station services running as far as Horsham (a double complication as it's on
two routes) and SWT have similar to Guildford, again a station served by
many routes.

Most of the Horsham services are not all stations from London, but fast
(ish) to Croydon for those via Three Bridges or Fast from Sutton -
Horsham for the other route (Peak services are different of course).
Horsham is a bit further than I had in mind, because of the fast
sections. Guildford is more complex, but there, most of the via Woking
services are not all stations, just the via Leatherhead ones; here
Woking might be the spot. As the OP mentioned, there will always be
boundary problems
