Oh man, you have good tastes - unfortunately, the only readily available FMP kits are horrendously expensive due to rarity, or D-Style, which are basically chibi/SD forms.
This is a great opportunity to talk about grades. HG/MG/etc.
If it says "HG" it means it's a High Grade kit. Decently engineered. It's 1/144 scale. It doesn't have a full inner frame and while it's usually well articulated, don't expect Olympic gymnastics.
If it says "MG" it means it's a Master Grade kit. This is basically all I build. There is zero difference in difficulty, just more parts. Usually has a full inner frame, or some type of inner frame, with opportunities to get very detailed if you want to say paint the armor, add some third-party metal detail-up parts, etc. Articulation is usually amazing.
The buddy cop Zaku and Dom from the OP are MG kits. They stand around 10" tall and have full inner frames. The Zaku is the Zaku II 2.0, and the inner frame for the 2.0 is CRAZY articulatable and detailed. If you want a bigger/more challenging build, the MG Zaku II 2.0 is a wonderful start. It comes with parts to build the normal version or the commander version with a horn, and if you're a Char fan, there's a Zaku II 2.0 in Char colors as well.
If it says "PG" it means it's a Perfect Grade kit. These require a little more care and a lot more time to build. Don't jump right into PG. If for no other reason, the cost alone should deter beginners.
That "really cool blue Zaku" is a Gouf Custom. It comes in several scales but after
a cursory look at Gaijin Gunpla's review, it looks like there aren't that many seams to fill. If you take a look at the upper torso armor, the sides of the chest don't have a seam to worry about. Meanwhile, take a look at the back of the legs. That panel line gap is an engineered seam - one leg part has the panel line gap, the other doesn't. When the two parts come together, there's no visible seam since it's basically a panel line.
I should also mention that using a gel pen on those panel lines (clean up mistakes/excess with Q-tips soaked in water or rubbing alcohol) is a great way to really make your kit pop.
Meanwhile, take a look at
this review of the HG Strike Freedom. Take a look at the lower legs, the beam cannons attached to the waist, and arms. There are very clear seams going down the middle of each lengthwise. These are parts coming together. If you just wanna build, by all means build! But if you wanna paint, you should at least cement them together if not fill them entirely.
Pick up an
HGUC Gouf Custom. It seems like a better option to take a shot at it if you wanna take a shot at just building a kit.
You will also need at bare minimum a halfway decent pair of flush cutters/side cutters/nippers. If you don't have a pair (and don't use wire cutters, those cause a lot of damage as they cut plastic nubs) pick
these up for $10.
Be clean with your cuts. If you really want an amazing result, use a fresh Xacto knife blade to gently shave the nubs down. If you take care, you turn a basic assembly into something you're really proud of and keen to show off.
If you're really into a clean build, you can get a set of sandpaper at Lowe's - 3M has a higher-grit set that I think starts at 600 - and sand the nubs down using a popsicle stick. I use Squadron flexible sanding sticks but we don't wanna turn this into "buy X, git gud" - start with the basics. Build the kit; you can always disassemble it with some care if you really want to.
This is a good tutorial on nub management, should you wish to undertake it.Edit: I should have probably said this earlier and will add it to my OP, but
Gunpla building is meant to be fun. It is not a race, it is not a contest. Never let what someone else says be what guides you. You are doing this for nobody but yourself. If you want to do more, there are always options to do more. If you like what you have, then let it be that way. It's way too easy - and I fall victim to this myself - to see some pro as fuck build winning contests, and then you look at what you're working on, then think "shit, I suck and should stop doing this." As a metaphor for life, this happens way too much to all of us at some point, and it behooves you to take things easy, at your pace, and start easy. Don't start hard.
Gunpla's closest allegory is golf: you are playing against nobody but yourself, it is an unnatural act that you have to get good at over time, help is always available, and your sole goal is to complete the course/kit.
