Let's not discriminate the real situation of the country. I've just screened a good chunk of the list of possible advisors because I'm maintaining several projects at disposal of associations without a business orientation to suspect my integrity.
It's possible to receive reliable advice that will only differ lightly with inconsistency towards gestorias notably (improvised unlicenced CSPs, which are not all worthless for having a terrain experience of running operations, some are competent), but almost never with lawyers which are very often cheaper anyway (gestorias can charge you 2 fold, seen almost 3 even 5 times more once).
If in doubt, crosscheck facts by applying willpower plus common sense. Initial consultations and remote ones are always free (never paid once and was never turned down for asking silly advice).
Also turn yourself towards the governmental initiatives & business clusters supporting orientation. There are phone lines and physical offices servicing as points of information to assist companies in their prospection through extensive support. Same at coworking spaces which can happen to have partnerships with the best gestorias then offering free counseling. Finally, speak to the community of expats already established. All blur will be cleared.
We're not talking of an intricated bureaucratic country like France but Andorra where the rules are stripped down and not a mind f**k to understand.
I've compared all available prices. Andorra should cost you no more than 6700 € for the initial setup (outside of the corporate capital), company plus residency paperwork & all official fees paid, including the assistance of the best lawyers or gestorias, then once in cruise mode, 200 € per annum in the specific case I described or 1000 € with a company (slightly more if numerous activities ran). Qualified accountants can be found starting at 30 € per hour at the lowest.
All things considered, adding Dubai should offer no financial edge until 100k or 150k (depending on the scenarios), then additional % benefits will start to climb up. Below with no perspectives of scaling, do not bother. In case of fluctuating revenues though, Andorra supporting less fixed expenses but some modulating tax arrangements will be more flexible with adaptibility than 0% : never an overpayment on this side of extreme.
Things evolve. Local multi-currency accounts can be free when feeding it with income with now free SEPA transfers or just at 13 € limitless of amount. The reputation of our banks appears to be half justified as old fashioned but also to receive more bad press than deserved, based on past appreciations. I have friends who tried UAE just to find out they were excluded from the PSPs of their choice targeted in EU, local banks found having cumbersome processes not exactly cheap, just to come back to Andorra and establish a side corp in UK or EEA instead. Globally, Andorra as center of operations is competitive. Only in rare circumstances, you'll be lacking, then you fix it with a patch.

Re OP, about
CFC applied in Andorra outside the scope of DTA :
"
Dividends and capital gains are exempt of taxation in Andorra provided the profits of the subsidiary were subject to at least 4% tax (not the dividend) in its domiciled country, the share holding is a minimum 5%, and held for at least 1 year. If exemption rules do not apply, taxes paid abroad will be deductible against Andorra
tax liability.
Also, a special tax regime can be obtained, which allows you to pay 0% tax on dividends and CGT, independently of the share % held by the subsidiary, provided the subsidiary has nominal shares (not bearer) and the subsidiary has paid at least 4% tax on profits."
