Getting "nice" water column blues

This has been annoying me for the best part of a decade so now im revisiting just thought id ask. Going back to basics after doing very limited UW photo for a few years and awaiting new housing.

How are people getting nice blue water column shots?

For reference im using Canon (RAW) and DS161 strobes (4800K colour temperature) and processing in Lightroom Classic.

Whatever default picture profile i use produces different blues but none "nice" They all tend towards green or on darker/bluer ones the saturation looks hugely excessive and the whole image has a cartoony look (im not adding any extra).

Typically shooting 1/160 to 1/250 and ISO 400 ish (any lower i cant seem to get enough strobe output. On 400 theyre 1 stop off full without diffuser. ish. subject dependent)..

Well aware of shutter speed controlling the background water brightness but this is specifically the hue and saturation i can never get correct.

WB is auto or daylight (but RAW so doesn't matter - i adjust after the event). I can get the foreground colours correct but not the ugly background.

A few examples. These are raws just spat out as jpgs with no editing hence messy look, deliberately to show what i mean.

First example the odd, saturated, fake look of the water behind. This in about 10m in indonesia. f/8 , 1/160th, iso400. Picture style "Adobe Colour"

Here the light/green hue and so on. f/8, 1/160th, iso400 @ 10mm. Nusa Penida...So its blue in reality.

Background just looks odd. Again saturation. f/8, 1/200th, iso400. Nusa Penida in about 15m

Similans somewhere.

Greeny, light blue. Not pleasing. 1/100th, f8 ISO200. Gili Air, Indonesia in 6m

Plenty of other examples. Shots deliberately not edited to show the default issues.

What are peoples workflows for a starting point "nice" blue? Ive tried standard, faithful, landscape (helps foreground, oversaturates background) with ideally Canon? What can i do to get the images less cartoony? Reduce foreground light too? "Camera Landscape" shifts towards blue but seems to over saturate at the same time.

FWIW the new "adaptive profile" run gets the water to a nice blue on most of them but its a black box. I have no idea what or how its doing it so dont like it instinctively.

Added bonus tips, less "vivid" or cartoony looking images. Which maybe lighting related.
