What are best charging practices & equipment for iPhone 7-Plus?

I just read this at this link. I'll assume it's correct or at least hope that it is and move on with life plugging my iPhone in to recharge as I sleep every night.

This new OEM battery (2,900 mAh?) is a dream. 👍

When to charge your iPhone or iPad - Apple Community

Charge whenever you want to, for as long as you want to. There's no reason to let the device drain completely before charging (in fact, it's a bad idea to do that on a regular basis), and there's no need to wait until it reaches 100% before removing it from the power source. You can charge when it's at 40% and disconnect when it reaches 80%, or any other values, without hurting the phone. And you don't have to turn it OFF to charge it; in fact, you shouldn’t. And you can leave it plugged in while using it if you want to.

The Best Practice, however, is to charge the phone overnight, every night. As it stops automatically at 100% you can't overcharge it doing this. You thus start the day with a fully charged phone.

Also, if you configure the iPhone for automatic backup using iTunes or iCloud, the phone will back up every night when it has a WiFi connection and is asleep.

Oops I goofed by mixing up Watts and Amps. I really don't know much about this type stuff but my original posting won't let me Edit this in.

I've found sites discussing charging rates & adapters for all of the iPhones. I see lots of different Watt adapters on Amazon and I'm thinking that maybe I could buy a couple.

USB Charger, Anker 2-Pack Dual Port 12W Wall Charger with Foldable Plug, PowerPort mini for iPhone XS/ X / 8 / 8 Plus / 7 / 6S / 6S Plus, iPad, Samsung Galaxy Note 5 / Note 4, HTC, Moto, and More https://www.amazon.com/dp/B07DFWKBF7/ref=cm_sw_r_oth_api_glt_i_dl_9FJ87A02WF50FZZRTPRC?_encoding=UTF8&psc=1

I haven't read your suggestions yet Rudegar but in playing around, I've noticed that my Battery Block is 25% faster at charging my iPhone if I use my short 4" long Lightning cord than if I either plug my 24" long, thick Lightning cord or my 4" long Lightning cord into that same 110v adapter which says Output 5.0 Volts 1.5 Watts.

That Battery app shows the charging rate (Amps) after it's been running for a few minutes and has raised the battery charge a % or 2. Here's what it showed me while using the 110v adapter:

and here's what it showed me while using the Battery Block:

No but could I ask for some very brief answers to my specific questions please?
