Pathfinder: Kingmaker is the most similar in a lot of ways, but is huge, has a boring and obstructive kingdom-control layer which promises much but adds very little, and yeah is very min-max-oriented. You’ll be presented with dozens of choices over and over again, and literally most of the things which look like “common sense” or “reasonable choices” are, ultimately, traps. Especially in the longer-term as the way it displays information, it doesn’t show you how failing to select X Feat will mean you can’t get Y Feat and Y Feat would be extremely powerful for you - indeed it won’t even (by default) show you stuff you don’t qualify for, so you just never know. All that said, though, if you play on Easy, or use a build guide on Normal (and don’t turn anything up - I’d recommend turning the kingdom layer down to Easy in all cases, as it adds so little, and harder settings just make it more random and/or require more secret knowledge), I think you’d be fine and find it fairly fun. It has a turn-based mode now, but is balanced in terms of frequency of encounters for non-turn-based, so it may get a bit wearing.
Pillars of Eternity 1 & 2 are both well-designed, don’t have the traps of PF:KM or even Solasta, and you don’t need build guides or any guides to make effective characters/parties. However, Pillars 1 is real-time-with-pause only, and Pillars 2 has turn-based, but has the same flaw with that as PF:KM - the frequency and type of encounters assume you’re playing real-time, so you get quite a lot of fairly easy encounters. The writing and visual design in Pillars 2 is particularly good, so there’s that.
DOS1 and DOS2 are both fully turn-based in design, but have their own problems. DOS1 is written like it was bad Terry Pratchett fan-fiction by a 15-year-old Northern European kid translated a bit literally, and is mostly actually about cheesing effect combos in combat. DOS2 is written like it’s edgy, smug, “dark fantasy” by a 20-something, and literally everyone in the game is an asshole. The combat is marred by a really irritating “armour” system which prevents people being hit by effects until you wear down their defenses, and has extreme gear scaling like an MMORPG which means priority #1 at all times is “find better gear”, and the difference between an incredibly hard fight and an easy one is more often gear than tactics (perfect tactics with bad gear will often have you barely survive, or even lose if the gear is bad enough - this is not true of any other game listed here, note). This is compounded by the fact that the game loves ambushes to an insane degree (there are good reasons for this but it doesn’t lead to fun). DOS2 is definitely better, but if the first one bored you, I doubt the second will thrill you, myself.
Baldur’s Gate 3 is pretty much “like Solasta but much better” (technically it’s slightly less faithful to some of the rules of 5E, but vastly more faithful to the classes, races, etc.), but it’s in Early Access with only Act 1 available and that seems unlikely to change until 2022.
One that gets overlooked a lot but might be worth a shot is Troubleshooter: Abandoned Children . It’s pretty unique - it’s like, basically the XCOM combat system, applied to what is essentially a JRPG (it’s technically Korean but w/e) in terms of progression and so on. It does throw a ton of terminology at you very early on, but it’s actually pretty transparent in terms of how things work. Anyway it’s implementation of turn-based combat is pretty great.
Wildermyth is another XCOM-influenced one (which RPS loved), and is pretty incredible, and very easy to understand, but doesn’t have tons of numbers and loot like more D&D-influenced games, rather focusing on the characters and a semi-procedural (or even fully procedural outside the five main campaigns) story.
There’s also the three Shadowrun games - Returns, Dragonfall, and Hong Kong. I’d only recommend the latter two - the first is just not a good game. Personally Hong Kong is one of my favourite CRPGs ever.
Beyond these there’s a lot of stuff that’s primarily tactics/strategy with some RPG elements, and stuff that I’ve played but can’t recommend like Wasteland 3.
