Training Program Request

I'm looking for a training program I can use.

My first goal is looking good (think Abercrombie & Fitch model good), with
strength as the second priority, and I'd like to strengthen my arms in
particular.

Currently I'm quite fit, but not particularly muscular.
e.g. my pecs are salient and not flabby, but not particularly large
I'm tall (1m90, 76kg) and probably an ectomorph.

I want a training that can "scale" up to my target and keep me there with as
little work as possible on an undefinite basis. Possibly that is going to
require two training regiment. That's fine.

My philosophy is that I want training to get out of the way - to be something I
do without having to think too hard about it.

I can subscribe to a gym membership, but I'd rather train at home. I own a
pullup bar and a set of one-hand weights. I can buy more equipment but my space
is limited - so no bench and barbells.

I want a 3-split training (3 days out of the week) as that proves the most
flexible for my schedule.

In terms of nutrition, I'm unwilling to tamper with my diet too much (which is
varied and healthy). I'm worried about protein intake, as I might be getting the
recommended 1g of protein per kilogram, but clearly not the 2/3g recommended for
gaining. It seems difficult for me to get that from diet only, so I'll probably
need to supplement with proteins (I'm looking for recommendations on this too).

In general, I'm open to supplementing insofar that it helps with my stated
objectives. On the other hand, I want to keep things simple, so the benefits
should be clear cut.

I already supplement 8g Citrulline Malate daily, which helps with unrelated
circulatory issues. I can adapt my consumption to benefit the training program.
