My opinion is that you seem to be grounded in what is realistic and practical. As your career progresses, you will have a better understanding of what you need to supplement the tools issued to you for the duties you are assigned. If you are in a rear Eschelon technical or support function, you might make different decisions than if you are in a unit likely to be the point of the spear.
When our son was "surged" into Iraq in 2004-"05, he was a platoon leader in a Marine reconnaissance unit (3rd LAR Bn). I have written here that I bought and gave him a plethora of rugged cutlery. Some were real gut-ripping throat cutters or deep stabbing daggers. What he chose to take were exclusively utility type blades ranging from a 7" fixed blade belt knife to several pouch or pocketknives. One was a Leatherman Wave. Today, I would have included one of the multitools focused on maintenance of an /AR based rifle. Note that others here on this forum may recommend against that.
My opinion: You are doing good. Give it time and you will be able to make more informed choices.
Best wishes.
