Too funny... Simply stating your file format is RAW is only half the equation... At least for some of Nikon's cameras. More specifically the Nikon D3x and D300 which when shot at 14-bit RAW cripples there frame rate...
On bright sunny days often I would shoot league soccer with my D3x which at the time had the highest resolution an amazing 24 mega pixels. However shooting 14 bit RAW limited CH (Continuous High) to a miserable 2 fps... While Nikon claimed 2.5 fps I was only getting 2! The version of Expeed the D3x used couldn't keep up with those "Huge" files however in D3x Manual they clearly state with 12 bit RAW you got the full 5 fps (and it does!). The exact same was true for the Nikon D300 with the MB-D10 Battery Grip... Strangely the D700 rocks 8 fps in 14-bit with the same MB-D10 Battery Grip... Totally LOVE my D700! it's a D3 in a richly featured package!
As for Auto ISO! it rocks in Manual Mode! That said I concur completely with Drbobcameraguy
"...I used to get into trouble with auto iso. Then I limited it to 1600. My D500 doesn't handle noise very well ..."
The difference between FX verses DX is HUGE! At so many levels... Case in point the D300 and D700 are identical in resolution and both come from the same era... However the high ISO IQ of the D700 is simple amazing compared to the D300 that I would never take above ISO 800... The D700 rocks all the way up to ISO 6400... and is absolutely stellar at ISO 3200.
Bottom Line? Read you manual folks and know what you tool can do and it's limitations...
I will say from my experience there is a nature progression in workflow as novice transition to enthusiast and finally there are a precious few actually become commercial photographers...
Food for thought... Photography is not a "Profession" it is instead a "Craft" there are no licensing bodies that govern this "Craft". While the Brooks Institute use to offer a Degree in Photography that train left the station years ago.... That said, Camera Vendors such as Sony, Canon, and Nikon use the term "Professional Photographer" in their market hype... For the longest time Nikon actually limited access to Nikon Professional Services to those who could validate that over 50 % of their income came from Photography!
Now they are more focused on selling this service to those with deep pockets...
2021 are hard times for Nikon... They are now seeking revenue stream (not so my industry recognition)

My Canon colleagues tell my that Canon does pretty much the same thing...
And they couldn't give a rat's butt on what mode you shoot in or what file format works for you... :)
All the best to everyone on the epic photographic journey!
