Doughnut-spending assistance please.

I'd personally wait for the Halloween update to come out which will be very soon, there might be something there that you might like

Wait for black Friday deals to come out, IMHO.

The best way to spend donuts is to not spend them rn.

Wait until Black Friday deals, unless there's something in the THOH event you really want.

A multiplier isn't much without things to multiply

I want everything. Then I'll decide what to keep out and what to store.

I tried MB's when I started and got mostly rubbish...

peeps ain't lying... the boxes return 7-8% per donut as an average. There are few better returns than that and none that pop up in regular play (ie outside of events). When you get another pond or Honda it can feel like it's all rubbish, but it's definitely the way to go if you want to raise your %.

You could buy almost enough Burns Mystery Boxes to raise your Bonus multiplier by 38%. You'd actually need 298 donuts to get the full 38%.
What's your multiplier now?
What level are you on?
Are you KEM farming yet?
I produce 150+ donuts a DAY. How? My multiplier is at 1905% and climbing. How did I get it that high? Mostly by buying Burns Mystery Boxes.

There isn’t a lot of content that isn’t again made available at some point. If I had my playing time over I would’ve spent every donut on mystery boxes from the start.

Which is why you buy lots of Blue, Purple, and Pink houses with game cash and make House Farms.
My testing game has a multiplier of 317.75% and a single Blue house pays out $1,881 per day. Regular payout on a Blue House would only be $450 per day. Since I have 61 extra Blue Houses together they pay out $114,714 per day.
People will tell you that house farms cost too much and take too much time to recoup the inflated prices. Wrong. House farms pay for themselves, then they start paying out buku bucks. I'll recoup the cost of my next Blue House in just 6 taps of my house farm.
I'm currently pushing my way up the levels to 939 by KEM farming. I'm gaining several levels per day and my income is still increasing.
And remember: I produce 150 donuts EVERY DAY in my regular game. That's enough to get an entire row of stuff from the Yearbook.
Every.
Day.

Oh, yeah. I almost forgot. If you've just absolutely got to spend some donuts on something try for Little Lisa's Recycling Plant from the Yearbook. At least that will earn you 450 Blueprints every 4 hours and take the grind out of the Railyard recycling system. And you'll earn 5 donuts every few days just by tapping it every 4 hours.
