The deeper you get into GBF, the more you'll start to realize that a lot of content demands specialized setups. As you get stronger and stronger, your toolbox increases, and it can be tough to have an idea of which tools to bring to which scenario.
I often recommend players look up setups, but beyond just glancing at Advanced Grids on the wiki, the proccess of finding them can often be nebulous and hard to understand, especially for a non-Japanese speaker.
Usually when looking for something, I begin my search on YouTube. Most good setups tend to have a reference video to go along with them, and you can often find "B-Tier" setups as well from players missing core pieces.
I also recommend you use the shown setup as inspiration. Just because someone recorded the setup and put it on youtube doesn't immediately make it good. Furthermore, no setup is immutable, and most of the time you can make reasonable facsimiles that will perform just as well. This should be your starting point, not the end goal.
Anyway, in this post I'll provide you with a small tutorial on what keywords you should be searching on YouTube to find what you need.
Generic Terms
Granblue Fantasy - グラブル
Guild War / Unite and Fight - 古戦場
Nightmare _ - _HELL (eg. Nightmare 200 = 200HELL)

Numericals
Japanese utilizes a numerical system grouping in the tens of thousands. The character for "ten thousand" is 万.
If, for example, you're looking for a 4 million honor setup for a raid, you'd type 400万 (400 x 10,000)
Raid Names
Proto Bahamut HL - つよばは (lit. "Strong Baha")
Ultimate Bahamut HL - アルバハHL
Grand Order HL - グランデHL
Dark Rapture (Hard) - ルシファー or ルシ (add HL for hard ver.)
Beelzebub - ベルゼバブー or バブ
Belial - ベリアル
The World HL - ワールドHL
Mugen - ムゲン
Diaspora - ディアスポラ (奥義100 for y100 setups)
Siegfried - ジークフリート
Seofon - シエテ
Cosmos - コスモス
Agastia - アガスティア
Super Ultimate Bahamut - スパバハ
Hexachromatic Hierarch - 天元
Dark Rapture Zero - スパルシ (lit. "Super Luci")
Some users will suffix HL to raids that otherwise don't have a non-HL version out of habit (eg. "コスモスHL" / "Cosmos HL").
For any othe raids, you can find the Japanese name in the respective wiki page, shown in the old TweetDeck display, as such:
Specific Items
If you're looking for setups using specific classes, characters, weapons, or summons, you can include their Japanese names in the search. To find the names, you can use the "Other Data" tab on their repsective wiki pages.
You can also "negate" by using なし (tl. "none/without"). For example, if I was specifically looking for a setup advertised as without Aliza, I'd use アリーザなし.
Example
Let's say I'm looking for a setup
For Siegfried blue chest (ジークフリート 400万)
In Magna (マグナ)
Without Aliza (アリーザなし)
We can add together all of these terms to find...
Huh, wonder who came up with that one.
