You say you don't want to min/max, but also haven't really said what you do want. This answer will cover what are optimal choices, and you can pick and choose what you wish to include or ignore.
Race
The first glaring issue this character has is race. As an Eldritch Knight Fighter using Charisma as their dump stat and intending to use plate armor, Tabaxi is one of the worst races you could possibly choose. The racial bonuses to Dexterity and Charisma are virtually useless, as is one of your racial skills (Sneak). Heavy armor doesn't use Dexterity at all, and you will always be rolling Stealth at disadvantage.
That said, obviously changing your character's race is a huge change of their roleplay and character, so you might not want to actually do it if you're really set on this race. And that's perfectly fine! But it is basically tossing your racial bonuses in the trash.
Ability Scores
Dexterity is a strange, and poor, choice to have as one of your highest scores. You state that you want to use plate armor and are picking the Eldritch Knight Archetype, your two main stats will be Strength and Intelligence, with Constitution as a close third. Dexterity offers you virtually nothing of value.
It increases Stealth (which you permanently have disadvantage at), it offers you bonus AC when using Light/Medium armor (which you aren't), and it allows you to roll +3 on Finesse weapons (which you already do, because of your +3 in Strength). Were I in your shoes and playing this character, I would do the following stats instead. This is assuming from your stats + racials that your rolled stats were 17, 15, 14, 14, 12, 7.
Strength: 17
Dexterity: 9 (7 + 2 Racial)
Constitution: 14
Intelligence: 15
Wisdom: 14
Charisma: 13 (12 + 1 Racial)
This gives you a wonderful opportunity at Level 4 to forego a feat and increase Strength and Intelligence by one each, raising them to +4 and +3 respectively, which is a large increase to almost anything you do.
Weapons
You are using two light, finesse weapons, one of which is a dagger. Daggers are, for every purpose (other than throwing), worse than another Scimitar or a Shortsword. You exchange a 1d6 for a 1d4 for no real benefit, other than the ability to at some point just throw your melee weapon at someone.
I would strongly suggest ditching the dagger and taking another scimitar as your main fighting weapon.
Cantrips
Light is... more or less useless. You get darkvision as Tabaxi, so there's an extremely limited number of situations you would ever use it in. I would definitely drop it.
Chill Touch is a fine choice, especially if you know you will be fighting Undead or other enemies with healing.
Take a look at Booming Blade, Green-Flame Blade, or Sword Burst for cantrips; they're pretty great options for a melee fighter. Personally, I would take Sword Burst.
Spells
Your spells are all great options. There's no "trap" spells that are actually terrible in your list. False Life is great, especially at Level 1, and both Shield and Magic Missile will be useful.
If your group has nobody else who is able to Detect Magic, you might consider trading False Life for it. If you want to increase your damage output, take a peek at Witch Bolt, which is a very nice damage spell. Otherwise, you can stick with those options and be very happy.
Class
You're playing a race that values Stealth, putting a lot of points and racials into your Dexterity, and are dual-wielding light, finesse weapons... yet you're playing Fighter. I would strongly suggest you take a peek at the Rogue class instead, because all signs point to you really wanting to play something like that, instead. Is there a reason you insist on playing Fighter?
While you can play a Fighter the way you are, it is very strange and much less effective to do so.
Ignore everything I said and have fun!
Okay, so there's a lot of things that your character does that aren't optimal; you've noticed that now. That being said, it isn't a bad thing. D&D is primarialy about you having fun, and if you are excited to play this character, then don't let anything I said deter you. Just keep in mind that if you are mostly looking forward to combat, you should prepare to be moderately disappointed with your performance. But if you really want to play a plate wearing scimitar wielding cat man who is really dexterous when out of his armor, go nuts. It's your character, and your game; enjoy it!
