There is a trilogy of book scalled "The Nameless War" by Edmund Barrett ( https://www.amazon.com/gp/product/B074C8KG27?ref_=dbs_r_seri... ) which I highly recommend if you like "Expanse" style technology and combat.

Written by a naval historian and features no super-weapons or other deus ex machina. Just solid strategy and tactics of Naval Combat in Space. There are two accompanying "Janes Ships of the Fleet" style books which detail the ships in the story.

It is 4/4.5 on the Mohs scale of sci-fi hardness https://tvtropes.org/pmwiki/pmwiki.php/Main/MohsScaleOfScien... (Jump drives, very limited FTL, and Plasma Cannons which are basically naval artillery in space)
