Often floats may land quite a bit later in the document than the point they are created, sometimes after a section break.
Is there a way to force a new section to start on a new page, after any unplaced floats?

Use the placeins package.
As noted in the comments, you can use
\usepackage[section]{placeins}
to automatically ensure floats do not go into the next section.
The package also gives you a \FloatBarrier command that you can use to prevent floats to appear beyond some point in your document. Use it as
% ... some floats here ...
\FloatBarrier
\subsection{My new subsection}

11@przemoc Note, however, that this doesn't seem to work for subsections. Commented Jan 9, 2014 at 13:10

2@FilipeCorreia, I added
\begin{figure}[!h]to the figure and it also works for subsections that way.– M. AliCommented Jan 30, 2017 at 11:46 -
4However, the
placeinspackage does not ensure that floats don't go into the previous section, i.e. a float with[t]may appear above the start of the section in which the float was specified.– WitikoCommented Nov 2, 2020 at 14:48
The command \clearpage will not only start a new page, but will also force any unset floats to be set before the page break. For documents with a left and a right page, \cleardoublepage does the same, but also ensures that the next non-blank page is a right hand page.
This is all independent of the section break, save that if you are using a class that does not put a page break before section breaks, this method will force them. But, from your question, this doesn't seem to be a problem in your case.

Simple. Full control. No extra packages needed. What else do you want? Commented Jan 29, 2016 at 16:53

5This is not a good solution, since it requires clearing things every single time, instead of defining what one wants once and for the whole document. It clutters up the code a little bit. Commented Jan 6, 2017 at 14:25

When I place this command before a new section, figures from there appear above section name. Commented Sep 15, 2020 at 12:20
I'm now using:
\usepackage{placeins}
\let\Oldsection\section
\renewcommand{\section}{\FloatBarrier\Oldsection}
\let\Oldsubsection\subsection
\renewcommand{\subsection}{\FloatBarrier\Oldsubsection}
\let\Oldsubsubsection\subsubsection
\renewcommand{\subsubsection}{\FloatBarrier\Oldsubsubsection}
This is shamelessly plugged from the union of this and other answers on the topic, plus this. As I can't comment yet (silly requirement, that..), I'm sharing it with via a new answer instead.
Edit: Plus, for the sake of copy-pastability for others, I've incorporated egregs excellent correction to use the non-argumented version of section redefinition (before, the snippet above read \renewcommand{\section}[1]{\FloatBarrier\Oldsection{#1}} etc. - Thanks, egreg

9Don't redefine
\sectionwith an argument:\renewcommand{\section}{\FloatBarrier\Oldsection}is sufficient and better, as it allows to still use\section*{title}and\section[Short]{Long title}. The same for\subsectionand\subsubsection.– egregCommented Mar 27, 2015 at 10:29
Code works well for all sections and subsections for me , package needs to be updated on miktex package library
\usepackage[section]{placeins}
\FloatBarrier
Above/Below every image or section
