Just got a new Nexus 5 phone only to realize it has no (easily) replaceable battery. So I'll need some tips to extend the life of the battery as much as reasonably possible.

I heard that unplugging the phone early as possible after it's fully charged is a good idea since the battery will lose trivial amounts of power over the hours prompting it to be recharged repeatedly many times. On the other hand, I also heard that letting the battery level run too low (say to 1/3 of capacity) too often will also hurt battery life. It seems fully charging the battery once or twice a day (and not overnight since you can't be there to unplug) might be the most optimal strategy.

Is there any truth or statistical significance to these claims?

No.
Leaving your phone plugged in overnight is perfectly acceptable and will lead to zero appreciable battery degradation.

Doesn't matter if it's a phone, camera, flashlight, drill/driver, or a trickle charger on a car battery. When a battery is charged, it's finished. Doesn't matter if you leave the charger connected or not. All batteries discharge even when not using them. [a lot slower of course] If you don't want to constantly charge the battery, leave the phone 'off'.

Bear in mind your battery has X number of charge/discharge cycles. Usually 400 to 500 before the battery starts to noticeably degrade. Topping it off uncessarily uses up one of those cycles. My son kept topping off his Galaxy S3 and the battery died after two years.

From what I read, let you battery get down to 20% for everyday stuff before charging. Of course there are times when topping off makes sense. Like before a trip.

If the N5 is the same as the N4, once it reaches full charge it stops charging completely and will not charge again until it's unplugged then plugged in again, it does not trickle charge. So it will charge to full then stop, if left on the charger the battery will eventually drop to the point where the phone will shut off.

Many Android devices work this way.

This. No matter how you treat you battery, generally speaking, they start to degrade around 18-24 months. Nothing you do is going to change that. Motorola will replace your battery for you. It's a pain but it only takes 3-4 days and isn't very expensive actually. Other companies will do the same.

Certainly one thing to not worry about...
