Concede, cause and conclude with C1 connectors — right mood, right register, out loud.
Three rules carry most of it. De ahí que always takes the subjunctive: de ahí que haya renunciado. De modo que splits by meaning — indicative for a result (llegó tarde, de modo que no entró), subjunctive for a purpose (habla bajo, de modo que nadie te oiga). Concessives like a pesar de que and aunque take the indicative for real facts and the subjunctive for hypotheticals — and register matters as much as mood: habida cuenta de que belongs in a report, o sea with friends, and mixing them in one sentence reveals your tone instantly.
Below: the connectors grouped by what they do, the mood traps, and a way to use them out loud in a real argument — no flashcards, no gap-fills.

Carla
Your grammar teacher for this pack
No connector lists to memorize, no gap-fills — in the Connector Pro lessons you argue small things out loud and Carla listens for the joints. She gives you the same sentence twice — aunque sabe, then aunque sepa — and asks you to justify what changed. She catches your third sin embargo in a row and has you rotate: no obstante, then ahora bien. And she feeds you a cause and waits for the consequence to arrive in the subjunctive: los datos son claros; de ahí que la decisión sea evidente.
Blank mid-sentence and nothing bad happens — she waits. That's the practice, without unnecessary judgement.
Quick answers
Yes — de ahí que haya renunciado, never the indicative. It's the academic way to say hence; in conversation the same job is done by así que ya sabés or a plain por eso te digo.
When it expresses purpose: habla bajo, de modo que nadie te oiga — so that no one hears you. For a result that already happened, it's indicative: llegó tarde, de modo que no entró.
Rotate: no obstante, aun así, ahora bien, con todo, así y todo. Translating every English however as sin embargo makes writing monotonous — varying the adversative is a C1 marker in itself.
Debido a que, dado que, puesto que, and in academic or legal prose habida cuenta de que and en virtud de lo expuesto — they outrank porque. The spoken counterpart is the informal es que….
No — always a pesar DE que. And keep register consistent around it: pick academic or colloquial connectors for a given sentence, not both at once.
