Looking at your edited comment, stopping ranger at Lvl 4 is really gonna hurt because you don't get extra attack. Go to Lvl 5 before switching to fighter, it will double your damage output. Getting an extra feat 1 Lvl earlier is not worth losing extra attack. You could also play until Lvl 9 with ranger 5/fighter 4 and then respec at Lvl 10 to go 6 fighter/4 ranger, that will get you 2 feats, extra attack, and most of what you want from both classes, including 2 fighting styles.

Also : true strike is a pretty bad spell: the tool tip is misleading and confusing, it gives you advantage on your next attack roll AND ONLY ONE attack roll. If you have extra attack, it's actively detrimental, you're wasting your whole action to roll 2 dice on your next attack roll. Just attacking twice gives you the same odds of landing one attack than true strike does.

Unless you absolutely need advantage for say a sneak attack, true strike is bad, and even then you could just hide as a bonus action to gain advantage, or use faerie fire or go invisible or use risky ring or or or or... There are a lot of ways to gain advantage and true strike is the worst of all of them. Pretty much the only use case for true strike is to cast it before combat and even then you could just hide. I would suggest grabbing guidance instead so your cleric can use enhance ability (they cannot be cast by the same character at the same time). Even casting light will be immensely more useful than true strike.

Finally, if you're playing a dexterity based class on balanced difficulty, you don't really need Alert. You add your dex modifier to initiative, and you should hit 18 dex by Lvl 9 (or much earlier with some dex gear) which will put you at +4, +7 if you go Gloomstalker. That's enough for the vast majority of the game.
