SPI advice requested

I am currently working on an 8-bit prototype (I can use any 8-bit MCU).
The four devices are all SPI:
1. Dallas Maxim - RTC - DS3234 (SPI). Most accurate RTC to date.
2. EverSpin - MR25H40 4Mb magnetic memory chip (SPI). SRAM speed (never wears out).
3. New Haven OLED Character Display (SPI). Insanely legible, clear, bright display.
4. I can use any PIC micro that has SPI communications.
Unfortunately, I do not know how to write to any of these devices using SPI, my hope is that once I get one of the devices working, the others will be similar to communicated with?
If you know of some example code that would get me pointed in the right direction, I would be most grateful.
I would also be happy to pay someone that could produce a basic Hello World with any of the 3 mentioned devices, just to get me started. I am a C/C++/C# software engineer (18 years and counting) Desktop and systems software for Windows.

    you only mention 3 spi devices.
    Microchip has some help in choosing which chip based on the features you want https://www.microchip.com/maps/Microcontroller.aspx.
    I would suggest you get one of the development boards with spi to see how it is done.

    You can try MCC with one of the supported MCU.
