Whilst possibly not exactly the UK Definitions, this Wikipedia article has a nice illustration-

Standard Broadband - Telephone exchange DSLAM - MDF - PCP - ( SCP ) - DP - home

or DSLAM - MDF - DP - home

DSLAM = DSL access multiplexer - broadband kit in phone exchange
MDF is Main Distribution Frame - where all the wiring meets up
PCP - primary connection point - where large multicore cables from exchange are connected to smaller multicore cables to SCP secondary connection points or Distribution points - telegraph poles or junction boxes underground.

FTTHoD is exactly the same structure as how Openreach deploy FTTH, except it is only done on an individual order basis, rather than a speculative basis.

And only where FTTC is already available to the particular end user.

My broadband basic info/help site - www.robertos.me.uk | Domains,website and mail hosting - Tsohost.
Connection - Plusnet UnLim Fibre (FTTC). Sync ~ 54.2/15.2Mbps @ 600m. - BQM

For FTTP, isn't the starting point more usually described as the head-end, or the NGA Handover node, rather than an exchange?

Yes, this node is normally in an exchange building.

However, I don't think there is a definite path from "Main Exchange" to "Local Exchange". The Local Exchange might be missed out entirely, have no head-end equipment whatsoever, and have none of the fibre routing that way.

The relationship between exchanges, in an FTTC/P context, is more often described as parent/child - where the child doesn't have the head-end equipment or handover node.

However, while the child's cabinets may be served by fibre terminating in the parent's active equipment, the fibre itself doesn't necessarily route via the child exchange building. Take a look at this old thread

Here's three factsheets with diagrams, though with different emphasis on internal/external detail:
FTTC
FTTP
FTTPoD

However, you'll probably find this link the most interesting, architecture-wise:
Presentation to BCS, on NGA Deployment Strategy, 2011

So, I'd do:

FTTP: Parent Exchange HO OLT - AN - Splitter - DP - Manifold - (X) - ONT - Router
FTTC: Parent Exchange HO OLT - AN - FTTCcab - PCP - (SCP) - DP - NTE - Modem - Router
ADSL: Local Exchange HO - DSLAM/MSAN - PCP - (SCP) - DP - NTE - Modem/Router

(X) - is the external splice tray on the premises. Not sure what name is given to this.
(SCP) - Some copper lines have a second cabinet in the path.
