My $0.02 on the discussion so far:
- Breadboards can have remarkably high internal resistance. Beware when
designing impedance-sensitive analog circuits, or when handling
high-speed signals, as this combined with parasitic capacitance can
really round off your sharp digital corners.
- Cutting perfboard down to size is easy with a pair of aircraft shears
(aka "tin snips"), so I've never seen that as a particular drawback.
- The card-edge tabs are pretty useful but be careful of how much board
there is on either side of the pattern; if you're hoping to plug into a
card-edge connector, be sure the connector you select allows the width
of the board (you may have to have extra contacts, or to trim the board)
- PCB design is a really, really deep topic that looks simple on the
surface. Go for it! Start simple and learn, learn, learn!
Cheers,

Jon,
Here is a link to an inexpensive bundle of perfboards for many projects:

The problem I have found with these perfboards over the years is the
need to cut them to size per project.
Here is a bundle of multiple sizes I've ordered before to give me a
selection for different projects - includes edge-card tabs:
/ELEGOO 32 Pcs Double Sided PCB Board Prototype Kit for DIY Soldering
with 5 Sizes Compatible with Arduino Kits/ ($10)

The following link has most of the same sizes of perfboards, but
includes screw terminals, male & female headers, and jumpers for only $2
more:
/Tnisesm Double Sided PCB Board Kits,with 40 Pin 2.54mm Male and Female
Header Connector, 2P&3P Screw Terminal Block Prototype Boards for DIY
Solderin/

You may also wish to acquire some card-edge connectors, both solder and
ribbon cable, to make plug-in circuits.
