Interesting that there has been no mention of side-slipping and yet that
would be my immediate thought if I believed I was too high to get onto the
ground without overshooting?

It depends on the glider. There are gliders which can be slipped very
effectively (e.g. ASK 21), there are gliders which can barely be slipped
(e.g. LS 4) and there are even gliders for which slipping is strongly
decouraged (e.g. LS 7 WL).
