The jacking points are basically a metal box about 3" x 4" x 5" (IIRC - but really just a guess at the size!), one end of which has an M12 thread for the 'pin' which goes down through the fibreglass cill. The inner face of the 'box' is spot-welded to the steel panel (the one with the huge holes in it) which run longitudinally inside the fibreglass cill.
As such, the panel takes the weight when the car is jacked up - which is why it needs to be solid.
Once the seats, carpet and underfelt are out of the way, you can see the metal frame across the front footwell where the flat floor slopes up towards the pedals, along the cill, and back again at the rear of the seat (along the bulkhead).
My rear crossmember was in good condition, as was the front one - so i only needed to work on the big flat panel along the cill (incorporating the jacking points).
When you look at it, it is obvious that the whole metal bit is bonded to the fibreglass bodywork, but it isn't 'buried' in fibreglass. It is glued to it with Sikaflex (or whatever other PU adhesive was used!).
You can access any rusted bits from within the footwell, or from under the bulkhead (not so easy, but still possible) to cut them away. Then it is "just" a case of making up some new metal bits, and welding them to the non-rusted bits in the car.
My jacking points were made from some 3mm galvanised steel sheet I had in the garage, and the cill bits were made from some other galvanised steel plate I had (possibly the back of the old tumble drier, I can't remember!!!).
I plug welded some of it, seam welded the rest, and my welding is never going to win a beauty contest, but equally won't fall apart.... but as it isn't visible, i don't care.
From looking at other posts on this thread it is clear that making it 'original looking' is very possible for someone with better skills than I have - but good enough is, well, good enough!

Just the one now, but this one's mine! - and it will be finished eventually..... - but also temporary custodian of a project until it is finished enough for Angie to drive it
...oh, and a 2006 Freelander destined for the jungles of The Gambia - 4500 miles across roads, desert and tracks - what could possibly go wrong?
