A6000 or A64000? For beginner to landscape photography

I'm interested in getting a nice camera that could produce good prints of landscapes to decorate my home. I know there are a ton of posts and comments on these two cameras and I've been reading them all (thanks r/SonyAlpha). The purpose of this one is asking whether I should jump on one of these two local offers:

A6400 with Sigma 16mm F1.4 DC DN - $700

A6000 with kit lens 16-50mm - $375

Both are advertised as light-use to unused. Both seem like really great deals!

I'm easily overwhelmed by the technical aspects of photography and lens options, I know I'll be on a learning curve. It may be awhile before I have enough skill for a nice landscape print, but this would be my foremost interest. Any other advice on how to approach landscape photography would be great! Where I live I expect low light conditions and subjects would be forest, coast, and mountains.

My budget is best bang for the buck that meets my needs, definitely under $1000 for a first set up, is this reasonable?

Thanks for your input!

Update:

Both cameras had sold but I just bought a very nice A6100 with a Sony FE 3.5-5.6 28-70mm with 1600 shutter count for $400. Might swap the lens out but a lot to learn for now!
