A June 4, 2019 paper from the LHC reviews a plethora of beyond the Standard Model theories, most of which are motivated by supersymmetry or grand unified theory (GUT) models. It is one of the more comprehensive and up to date available reviews of such models.
Every single one of these theories is completely wrong.
These theories are the Lotus eater traps of modern physics that should be dead on arrival and summarily rejected in any serious effort to understand our reality.
Not a single one of them can even reproduce all of the particles of the Standard Model, without creating any particles that are not observed, or phenomena that have not been experimentally ruled out.
The more compliant supersymmetry (SUSY) models are with experimental constraints, the less well they achieve the purposes for which they were designed.
It shocks me, to some extent, that it seems as if almost no one has even seriously tried to produce a model with no right handed neutrinos, no extra Higgs bosons, no other new fermions or bosons, no dark matter candidates, three generations of fundamental fermions, and that preserves baryon number and lepton number.
But, perhaps this is simply because the entire enterprise is doomed, and ill motivated by observational evidence in the first place, and it simply can't be done.
Some of these models explain charged lepton flavor universality violations (usually with leptoquarks), which is pretty much the only significant anomaly between the Standard Model and observation that hasn't been ruled out (or seems likely to be ruled out soon based upon what we know), but even if the anomaly turns out to be real, my own sense is that the solutions proposed to explain these anomalies are almost certainly not the correct ones.
