IMHO, you'd be much better off making a more purposeful build. Weapons are very much a personal choice, depending on whether you want fun or earnings rate and how long you want your play sessions to be.
I prefer all lasers for PvE because the earnings rate is higher overall and I prefer long play sessions without having to waste a lot of time going back for ammo. The time to kill is longer in theory, but if you set your fighter on the enemy and wait for it to land a shot, the enemy will prioritise the fighter, so you get complete freedom to shoot it from the side, where you can target its powerplant and kill it before it even knows you're shooting it. That works for any ship bigger than an Asp. The fighter must be the one with fixed multi-cannons, which stops the enemies from chaffing.The one with fixed plasma works as well, but doesn't seem to do as much damage as the m/c one.
Generally, bi-weave shield are better for PvE, where you want to kill multiple enemies. Prismatics are OK for shorter sessions, but you need two very large shield cell banks to keep them charged, which those builds that you've been looking at don't have. SCBs need cooling, so you'd have to fit heatsinks or thermal vent lasers too. Overall, correctly engineered bi-weaves give more shield strength because they replenish more quickly and give more hitpoints. Always engineer with fast charge.
Here's what I use for PvE. If you don't have Guardian shield boosters, you should prioritise unlocking them, which can be done quickly with a DBX fitted with two point defence and an SRV. If you want to farm materials while shooting enemies, you can change one GSB for a class 7 cargo rack and one class5 GSB for a 5A collector limpet controller. The armour isn't really necessary because you'll never lose your shields, so you can save 1/2 billion r and get some extra speed, which might be more useful.
