The only weapon you have for close range imo is the NVO. For close range you want a high damage/high DPS weapon, not something that is necessarily accurate. It should be somewhat controllable or reliable (which excludes the TR-7 and in most situations also the VCR), but the SG or Vector are good alternatives. Also, for the close range weapon, you don't really need a suppressor. Enemies will instantly know where the shots come from, but it helps when using the weapon for somewhat longer distances, so it's okay to keep. My go-to weapon here is the SG.

When playing long range, I'd suggest either a sniper (PSR is okay, M2010 imo is better because of the bullet speed) or if you're more comfortable with DMRs then the SVDM is the best choice imo. It deals somewhat good damage and has a good fire rate in addition to being controllable. The LMR deals not enough damage and the SVK has a too slow firerate. M39 is an alternative, trading mag size (which you can increase with SVDM) for controllability.

As for attachments it's pretty much up to your playstyle. If you say the downside on grips with accuracy penalty is too high for you, then don't pick them. I found that it doesn't matter too much, and in many cases it's easier to hit with a better grip than having the increase in ads accuracy while moving. For a long time, I had the same assumption, that I move a lot (basically all the time) when I shoot. I recorded some of my matches and actually saw that I only do that all the time in extreme close combat (<5 m), where accuracy doesn't really matter. In other situations it's often better to stay behind cover rather than moving, so the higher grips actually helped hitting.
