I have to say: I am a bit confused by at this point T__T
First, thank you all for your comments.

Let's try and clarify:

1) I would like to use this solenoid: https://www.adafruit.com/product/2776 It is a 5V.
I would also like to try this one: https://www.adafruit.com/product/412
This is a 12VDC. BUT, for the time being, I will be happy to just figure out the 5V. Once it works, I will also consider the 12V.

Not trying to confuse you but my solution is to use an Arduino relay module, like this
Probably a great idea but I have no idea of how to use one of those.

Absolutely wrong.

The threshold voltage is not relevant here.  You need a logic-level mosfet, and the IRF3205 is not logic level.
So, I should go back to the TIP120 idea? As you (MarkT) were saying here:

A logic level MOSFET with 0.3 ohms or less on-resistance will be perfectly fine.

The TIP120 from a 6V supply and with 1k base resistor would be fine
4) If I use this: https://www.adafruit.com/product/1466 as suggested by silly_cone, then can I just connect to the barrel of the Arduino? Probably that is not a good idea, right?
