I am looking for a good overview of the Royal Navy and its operations. N.A.M. Rodger's two volumes end in 1815 and I am more interested in the 20th century. I know Robert Massie's Castles of Steel is recommended here often but I read his Dreadnought and was driven mad by all his digressions about private lives of this admiral and that politician so I'd like to avoid that.
I think what you probably are looking for would be the official operational histories of the Royal Navy in WW1 and WW2, both of which are in print from Naval Military Press and able to be acquired (although they aren't cheap).
The official history of WW1 is here: https://www.naval-military-press.com/product/official-history-of-the-war-naval-operations-five-volume-set/
The World War II official history volumes are here (they're the "War at Sea" titles): https://www.naval-military-press.com/?s=Roskill&post_type=product
The good news is that if you don't mind reading these books online (and aren't a bibliophile like me who wants it in their hands), you can read all five volumes of the WW1 history for free here: https://www.naval-history.net/WW1Book-RN1a.htm
Whilst it covers the entire period of the Royal Navy’s existence- and its English predecessors before that- i found ‘Empire of the Deep’ to be great for providing an overview of both operations and attitudes for the 19th and 20th century. The author focuses on Jackie Fisher, especially, to illustrate the birth of the ‘Modern’ RN. It’s a bit wider than the subject matter you cited, but it’s definitely worth a read If you’re interested in the Royal Navy.

It all depends what you're looking for, but I found James Goldrick's Before Jutland: The Naval War in Northern European Waters, August 1914–February 1915 a very enjoyable read. To quote my own review: "In addition to being an engaging writer and and experienced researcher, Goldrick is a retired admiral in the Australian Navy, and have himself spent time sailing the North Sea on joint operations with the British Navy. His take on the challenges facing British naval planners and commanders tasked with conducting operations in European waters during the opening stages of the Great War is therefore somewhat different from that of traditional academics."
