Congratulations on the new (to you and your wife) LEAF!!
I'm thinking you'll be very happy, especially if you operate it within the parameters you've outlined, a 45 mile round trip.
In my opinion, you don't have to rush into getting a L2 charger installed. I went for many, many months with just using L1, and others here still use L1 exclusively. I just eventually got upset thinking about the decreased efficiency of L1, which is about 10% or so less efficient than L2, so I installed a GE Wattstation, which has a cord and was a plug-in operation, as I had pre-wired the garage when it was being built. Some of the experts don't like the GE Wattstation, I think it got a poor reputation because of Nissan, there was a software update Nissan installed, and I haven't heard of any problems since. I don't know what the price of the GE Wattstation is vs. others. One other option is to send the OEM L1 charger to EVSE Upgrade,
https://evseupgrade.com/ which is run by Phil, a brilliant guy who has contributed a great deal to the EV world.
One other bit of advice I have is to open the hood, look to the left and the right, there are two little plastic covers covering the struts. Carefully remove those covers to see the strut threaded portion with nut, and clean out all rust and water sitting in there as best as possible, and put some grease in there to prevent further rusting. Somebody else here pointed this out, and I was upset when I looked at my 2011 and saw how bad it had gotten.
The only other bit of advice is to keep the battery cool, or at least as cool as possible out of the hot sun on an asphalt pavement, and don't have it hot and fully charged any longer than necessary. It seems the battery can get hot, but if it hot and 100% charged the degradation is dramatically faster than either just hot or just 100% charged.
Keep the tires inflated to about 42 p.s.i. or so and they should last a decent amount of time. My OEM Ecopias lasted 45K miles, and I was happy. In the LEAF, Low Rolling Resistance tires are important, both for range and to lessen to a small extent wear and tear on the main costly item, the battery.
Good luck with everything.
