You might have the fussiness for a while. It can be very frustrating with the sheer amount of wasted food.
It probably went much quicker for Archcat because he was a rescue boy who had lived for an undetermined amount of time on the streets, and was presumably well used to catching and eating whole prey for his survival. The first time I gave him raw chicken I mistakenly gave him a whole bowlful and he vomited the entire thing up again at night - on my rug, semi digested. Hence the warning to take it slowly.
Going part raw was a measure of desperation, because I realised he needed to exclude grain-based foods, but he has always flat out refused to eat anything from a can, including really high-quality brands like Macs, Grau and Lillys Kitchen - so I was forced to look for an alternative.
The advantage of keeping part raw, part wet and part dry really is that you can change the proportion round a bit of you run out of one of them. And our cat sitter refuses to feed raw food so when we were on holiday we just gave him wet and dry that week. In the long term I would be more concerned about feeding a boy cat exclusively (or a high proportion of) kibble than a girl cat, because of the risk of kidney crystals developing.
Each month I buy a few kilos of various frozen raw meats from a special raw food shop for dogs and cats. It's usually pre-diced, but some companies will mince it for you too. I also get a bag full of chicken necks, but I know some raw feeders prefer chicken wings. Then I defrost each day's portion the night before in the fridge. I put the defrosted food in his bowl, sprinkle a small amount of taurine powder over and mix it in with tepid water to make a brown sauce for the meat. That has the advantage too of increasing the amount of liquid the cat drinks (which is another danger with exclusive kibble feeding).
I know other raw feeders choose to make up a kilo of meat in advance with various supplements and a few added veg, then freeze it in daily portions. I find that too much hassle though.
Two warnings: you should never feed chicken bones that have been heated in the microwave, because there's a danger they'll splinter and cause choking, and you should never feed raw pork as it can contain a potentially fatal bacteria (for cats only).
