Need help picking 32GB of fast DDR4 memory for Adobe Lightroom processing

I'm trying to pick 32GB of memory for a custom build on a computer that will primarily be used for Adobe Lightroom and Photoshop image processing. I'd like to overclock the memory to at least 3600MHz on a ASRock Z390 Extreme4 motherboard.

These are the sticks I can find to choose from:

3600/16 (4x8), G.Skilll Trident Z, $452.99
3600/16 (4x8), Corsair Dominator Platinum, $499.99
3600/17 (4x8), G.Skill Trident Z, $383.99
3600/17 (4x8), G.Skill Ripjaws V Series, $369.99
3600/17 (4x8), HyperX Predator, $499.99
3600/17 (2x16), G.SKill Trident Z, $490.90

3200/14 (2x16), G.Skill Trident Z, $399.99
3200/15 (2x16), Corsair Dominator Platinum, $339.99
3200/16 (2x16), G.Skill Ripjaws V Series, $269.89

The first numbers on each line are speed/latency.

Which would you choose and why? I don't have any reason to ever think I'll need more memory beyond 32GB in this computer so I don't mind limiting future expansion and picking 4x8 sticks. For some reason, it appears that the lower latency sticks at 3600MHz are only available in 4x8, not in 2x16.

If you calculate out the latency in ns, the 3200/14 sticks are a tiny bit faster than the 3600/16 sticks. But, obviously the transfer speed is a bit slower at 3200. Not sure which matters more for an application like Adobe Lightroom.

3200c14 kits are capable of overclocking to 4000MHz easy enough if the MB can handle it which with 32GB that MB will probably hit its limits around 4000MHz with 4x8GB or 3733 with 2x16GB if the QVL is any indication.

G.SKILL TridentZ Series 32GB (4 x 8GB) F4-3733C17Q-32GTZKK $369.99

G.SKILL Ripjaws V Series 32GB (2 x 16GB) F4-3200C14D-32GVK $329

Thanks for the info.

I don't quite understand your first linked product. The first is a 4x8, 3733/17 for $447.99 which doesn't seem like a great deal. What were you trying to show me here? Did you see this for $369.99? That isn't what Newegg is showing me now. It's also CAS 17 (I guess I was hoping for 16). Am I missing something with this recommendation.

The second is 2x16 3200/14 at a great price $329.99 (on sale for a few more days). This looks like a good choice if I for for 3200 sticks.

Edit: I just found the 3733/17 (G.Skill - Trident Z 32 GB (4 x 8 GB) DDR4-3733 Memory - F4-3733C17Q-32GTZKK) here.

Hmm price went up on that kit since I posted.
3733C17 will have a similar latency to 3600c16 but extra bandwidth.
