@graziame My recommendation is at chapters 1-5 concentrate on your progress through the research tree and completing enough provinces throughout so that once you reach the end of the chapter you do not have a blockage. I do recommend participating at a certain level in tournaments to acquire more relics. Here I would recommend using troops to fight (2-4 provinces or what you are comfortable with) each day and once you cannot fight, finish the province with a negotiate then stop until it unlocks again the next day.
For events, save currency for the daily prizes that are post useful for you - wishing wells are helpful simply for the diamonds that will allow you to upgrade your Builder's Hut to level 3 and your Magic Academy as much as you want. All other event buildings at this level are to me replaceable unless you adore it for whatever reason and gain Royal Restoration to upgrade it.
Spire is interesting, but for the most part I don't participate in it because, for me, it is a resource drain that does not benefit me.
On events - once you start hitting chapters 5+ you may have the ability to do more for events and have the space to dedicate some level 1 workshops and factories to make them easier.
Quite simply, there are so many events regularly beyond Tournament that it is very easy to get burned out by them.
