For me, Round Turn + 2 Half Hitches (locker and keeper) is the basic benchmark hitch that all right angle hitches should be measured by!
.
But, if making RT + 2HH; would seem easy enough to take extra tuck for Anchor +1 HH(keeper).
If in a bight or end in an eye; i actually like a carabiner as keeper position rather than HH.
.
But, my next basic choice here would extend to taking the aforementioned Clove to it's sibling a 'Bag Knot', quite possibly 'Double Bagger' + keeper (HH or carabiner).

This Crossed Turn start (i see as variant of RT) and Best Top Nip(in key equal/opposite SPart position) lock make this choice more secure;
and if all stops come from the crossing lock, and keeper doesn't deform SPart (just forms a failsafe, carabiner hangs loose around SPart)i'd think would be stronger on larger host mounts where size of smaller host itself negates any added strength/host dictates strength/retained usable tensile against load.
Normally, (Slipped)Bag is one of my mult-purpose faves; especially how maintains on 'squareness'; it also functions backwards; but mechanically different force flow in reverse (to my eye).
.
Though if grooming lacing for strength; would always start with Turn over host mount;
then 2-3 Turns around SPart (to form 'boot' or swelled 'grommet' at main breakpoint' of highest loaded deformity:where SPart enters the knot's inner workings ; then back over host and kinda back around and thru (will have to draw) to then lay next to SPart and make keeper to it. (in the spirit of ABoK#1669 :"The FIGURE-EIGHT HITCH and round turn. If the rope is weak and the hoist is heavy, a round turn on the standing part adds materially to the strength of the knot." but different finish).
.
i think a single/simple Turn around SPart deforms it only; at it's most loaded part.
>>a Turn is like open hook, only hits 1 side of mount, takes a RT (Round/Real Turn) to make as full 'tang'(knife reference) as your eye says it is!
But, more Turns help to mitigate the deformity and give 'strength' back.
A single Turn pulls concentrated at 1 point across linear axis of SPart length;
RT+ pulls more along SPart length at multiple points .
This is more notice-able when Dbl.RT around SPart, doesn't just slip down to seat against host mount;
but rather can 'float' or be set away from host mount (imparting some dynamics in line mechanism also);
to me showing can be alternate support leg for part of forces at some point.
Volume of force is finite, so any routing thru alternate; isn't carried on 'main' so much.
Friction hitch used around SPart for this with less than 15 degrees deflection to SPart and no deformities to SPart should be max(?) strength.
