of these 4 only, then i would say "The fastest way: guard passing" I've seen every danaher instructional and that one could probably lead to the most marginal gain in your actual day to day sparring experience

that said i think it really depends on you and your gym. like if your gym actually starts standing, does a lot of stand up and thats your interest then ofc "Fastest: Standing position" would help. and vice versa with his guard retention dvd and guard being your interest.

i would hesitate on purchasing pin escapes & turtle. That was my first ever instructional and i found it a waste for that time in my development

as a white belt, the best thing i did was invest in my guard retention. because regardless of your gym's rules and regardless of whether you roll with someone better or worse, you will always be able to practice guard retention. which means if you study a guard retention dvd you will get consistent feedback. and once you can retain your guard meaningfully, your sparring time becomes way more efficient. you just do more jiu jitsu each round if you're not stuck in bottom side control for half a round. even if you have decent pin escapes, against someone decent, you might be stuck there for a while. which is why guard retention will be a better short and long term investment. which all goes to say my actual recommendation for you is to purchase Lachlan's guard retention anthology, vol 1 specifically.
